To put it simple, the series was very well-written and funny as hell.

But now, let’s take a look at some hilarious moments that weren’t meant to make it on screen — what we call bloopers or goofs. There’s one particular scene that really surprised me; a scene that wasn’t edited out and features an unexpected blooper.

June Cleaver’s calendar

One well-known mistake, which I had never heard about until now, involves June Cleaver’s calendar. Over the years, the Cleaver household has been presented as the quintessential example of good housekeeping.

Every organized and well-planned home, of course, has a calendar to keep track of important dates. June Cleaver certainly had her calendar, but it seems they forgot to update the one hanging on the wall of the Cleaver home.

For those with sharp eyes, you can spot that June Cleaver’s calendar displayed incorrect dates in the episode The Poor Loser, from 1963. In fact, the show likely used a calendar from 1961.

In the same episode, Ward and Beaver are set to go watch a baseball game. During a close-up of the tickets, there’s a noticeable error: “Mayfield” is misspelled as “Mayfied” in the smaller print, even though it’s spelled correctly in the large print.

The fake bee

In earlier times, special effects were far from the efficient technology we have today, and filmmakers had to rely on more analog methods. For those of you who remember the episode The Silent Treatment, you might recall a scene where Beaver is painting a door and a bee suddenly takes an interest in him.

Naturally, using real bees posed significant challenges, so the production team resorted to a fake bee hovering on a string. If you look closely, you can clearly see the string bouncing around Beaver’s face!

“I got in a lot less trouble”

Jerry Mathers portrayed Theodore “Beaver” Cleaver and quickly became everyone’s favorite kid brother. The actor, who celebrated his 76th birthday in 2024, remains alive and well.

He has also been asked whether his off-screen personality mirrored any aspects of Beaver’s character.

“Well, I got in a lot less trouble,” he laughed. “But then again, I had a lot of people watching me all the time. Because when I was due doing the show, there were about 60 men and probably eight or nine women on the show these were lighting people and all the different things that they have to do to make a series. Between takes, when I wasn’t doing things, they would come out and we’d play — throw footballs, throw baseballs. It was like an extended family. There was a whole bunch of people, and they wanted me not to say, ‘I don’t want to be here anymore.’”

Jerry Mathers’ infamous audition

When it comes to Jerry Mathers, one can’t help but mention his infamous audition for the role of Beaver. He made quite the impression — let’s just say it was memorable.

“I came dressed in a Cub Scout uniform, so that should have been a big clue,” Mathers recalled.

The young boy was supposed to head to his Cub Scouts meeting right after the audition, and he wasn’t particularly enthusiastic about being there. However,he quickly impressed the show’s creators, Joe Connolly and Bob Mosher, with his natural charm, innocence, and ability to deliver lines authentically.

Mathers candidly expressed his concerns about missing his Cub Scouts meeting, which only added to his charm. The producers found his honesty refreshing and knew immediately that he was the perfect choice for the role.

Ironically, there wasn’t much time for scouting for Mathers after he landed the role of Theodore.

“We had to go to school for three hours a day, and it could be chopped up, because we’d go out and if they’d shoot the original, the long shot, and then we’d do closeups. You were jumping in and out of school all the time, and you’d come back 20 minutes later and you study for maybe another 40 minutes, and then you have to do another scene or whatever,” Jerry explained.

Negotiating genius

Jimmy Mathers was a trailblazer in more ways than one; he became the first child actor to negotiate a deal that entitled him to a slice of the merchandising pie from a TV show. Talk about smart business moves!

This savvy decision turned out to be quite the cash cow, as Leave It to Beaver continues to rake in revenue more than 60 years after its original run. Who knew that a show about a kid in a striped shirt and his misadventures could keep making money long after the final credits rolled?

Tony Dow was not the original Wally

Actor Tony Dow is best known for his role as Wally Cleaver, the quintessential All-American older brother to Theodore “Beaver” Cleaver and son of Ward and June Cleaver.

In the beloved series Leave It to Beaver, Wally navigates the ups and downs of teenage life, tackling relatable issues like dating while offering guidance to his more mischievous younger brother, Beaver.

Dow’s portrayal of Wally was nothing short of iconic; his charm, warmth, and relatable persona helped make Wally a household name. But did you know he wasn’t the first actor cast in the role?

The pilot episode originally featured Paul Sullivan as Wally Cleaver, but he was replaced because a sudden growth spurt made him appear too old for the role.

June Cleaver’s hidden scar

Barbara Billingsley, best known for her role as June Cleaver, will forever be remembered for vacuuming the Cleaver living room while impeccably dressed in high heels and pearls.

Her portrayal of parenting was characterized by calmness and respect, setting a new standard for family-oriented sit-coms.

However, there’s more to June’s trademark look than meets the eye. The actress wore her iconic pearls to conceal a surgical scar at the base of her neck that she preferred to keep hidden. As for the high heels, they were a practical choice to maintain height parity with her growing sons.

Did Jerry Mathers and Tony Dow get along?

Studying photos from the Leave It to Beaver set reveals the undeniable bond between Tony Dow and Jerry Mathers.

”Wally is the perfect big brother,” Jerry Mathers said in a 2006 interview with the Television Academy Foundation.

“He’s the champion basketball player, football player. He does everything right. He’s a huge letterman. He gets A’s on all his papers. Everyone loves him.”

Their connection shined through in their eyes and body language, showcasing the genuine emotions that made their characters resonate so deeply. It’s hard to portray such strong sibling dynamics without real feelings behind them.

For those curious, Tony and Jerry truly became best friends during filming and maintained that lifelong friendship.

Following Dow’s passing in 2022, Mathers expressed his grief, saying, ”He was not only my brother on TV, but in many ways in life as well. Tony leaves an empty space in my heart that won’t be filled.”

Jerry Mathers was not killed in Vietnam

Did you know that Jerry Mathers was once rumored to have died in Vietnam? Thankfully, that was just a false report.

The young actor was never in Vietnam. Although he attempted to enlist in the Marines, he was turned down due to concerns that sending him overseas could lead to negative publicity if anything happened to him. Instead, Mathers enlisted in the Air National Guard, where he spent his service time in the United States.

The most expensive episode

One of the most legendary episodes of Leave It to Beaver aired on May 5, 1961. In a memorable scene, Beaver climbs up to prove that there’s no soup in a giant cup on a billboard but accidentally falls in.

This particular episode had a production cost of $40,000, making it the most expensive of the entire series. It also became one of Jerry Mathers’ most memorable episode, as he struggled with a fear of heights.

Toilet on screen

Leave It to Beaver was groundbreaking in many ways. One of the show’s unique aspects was its focus on the children’s perspective, which allowed viewers to connect with the characters on a deeper level. Another significant feature was its ability to highlight everyday aspects of family life.

This was notably exemplified in an episode where Wally carries a toilet seat, marking a pivotal moment in television history.

Even if only the tank was visible, it was among the earliest programs to showcase a bathroom in any form. In the 1950s, networks were extremely hesitant to display bathrooms on television, let alone an actual toilet.

The first episode almost never made it on air

The first episode of Leave it to Beaver was banned from airing due to its content involving an alligator and the portrayal of a bathroom, which was not allowed on television at the time.

In the very first episode, Wally and the Beaver decide to buy a pet alligator. Jerry Mathers recalled, “We were going to put it in the toilet because we knew alligators needed water. At that time, you not only couldn’t show a toilet, but you also couldn’t show a bathroom on television. It was prohibited.”

The show’s producers battled with censors to include the bathroom scene, ultimately reaching a compromise to only show the back of the toilet tank. “That was a way that Leave It to Beaver actually set some precedents for the television industry: We were the first show to depict a bathroom,” Mathers explained, talking with Fox News.

No laughing policy

The show’s creators sought a gentle comedic tone, they preferred elicit chuckles rather than uproarious laughter.

This intentional choice played a significant role in shaping the show’s unique atmosphere, fostering a warm, family-friendly environment.

The producers believed comedy should stem naturally from the characters and their interactions, avoiding exaggerated jokes or over-the-top humor. As Tony Dow put it: “If any line got too much of a laugh, they’d cut it.”
