If you grew up watching Sesame Street in the 1970s, there’s a good chance you remember a wild-haired purple Muppet who thought every terrible joke was the funniest thing anyone had ever heard.
That was Harvey Kneeslapper.
Harvey would wander up to an unsuspecting victim, set up an awful pun, pull some ridiculous prank and then completely lose his mind laughing about it.
He was loud, annoying and strangely unforgettable.
But like quite a few of the lost Muppets of Sesame Street, Harvey eventually disappeared from regular appearances. The Lost Muppets of Sesame Street
So what happened to Harvey Kneeslapper?
Who Was Harvey Kneeslapper?
Harvey Kneeslapper debuted on Sesame Street in 1971 and was originally performed by legendary Muppet performer Frank Oz, who also performed characters including Bert, Grover and Cookie Monster. Harvey’s original run lasted through the 1970s.
Writer Norman Stiles created Harvey, and Stiles later recalled that Harvey was the first character he created for Sesame Street.
Harvey’s specialty was practical jokes built around letters, numbers and terrible puns.
He might ask someone where he wanted to “B,” only to slap a giant letter B onto them and erupt into hysterical laughter.
It was silly, simple and exactly the kind of strange comedy that made classic Sesame Street considerably weirder than many people remember. Before Elmo: When Sesame Street Was Wild & Weird
Harvey’s Laugh Was Brutal on Frank Oz
Harvey’s laugh was probably his most memorable feature.
Unfortunately, it was also one of the reasons the character didn’t last.
Norman Stiles later explained that Frank Oz was straining his voice from all the laughing required to perform Harvey. Stiles also recalled that the character annoyed some people, and eventually everyone felt Harvey should take what he jokingly described as a “long vacation.”
Frank Oz himself was even less sentimental about Harvey.
When asked about the character years later, Oz said Harvey seemed like a funny idea initially, but performing him was exhausting. He also felt the character simply wasn’t funny enough to sustain indefinitely.
That brings us to Harvey’s other big problem.
Harvey Was Basically a One-Joke Muppet
Characters like Bert and Ernie could be placed into almost endless situations because their personalities and relationship created new comedy.
Harvey had a much narrower formula.
Harvey approaches someone.
Harvey sets up a pun.
Harvey pulls a prank.
Harvey laughs like he has just invented comedy.
Repeat.
It worked wonderfully in short sketches, but eventually there were only so many variations the writers could create.
Oz later pointed to the relationship between Bert and Ernie as an example of why those characters had longevity that Harvey didn’t. There was simply much more to explore.
Harvey wasn’t the only Sesame Street character to eventually fade away. Characters such as Forgetful Jones also became much less prominent as performers, writing styles and the show itself changed over the decades. Read about Forgetful Jones and his Sesame Street history
Was Harvey Kneeslapper Banned?
No.
That’s an important distinction.
Harvey wasn’t removed because of some major scandal, and there isn’t evidence that Sesame Street officially “banned” the character.
His disappearance appears to have been much simpler: the character was exhausting for Frank Oz to perform and there wasn’t enough creative range in the concept to justify continuing him.
Sesame Street does have a fascinating history of episodes and segments that were actually pulled, altered or withheld for various reasons, but Harvey’s story isn’t really one of them. Banned Sesame Street Episodes: The Untold Stories
Harvey was simply retired from regular use.
But Harvey Never Completely Disappeared
Here’s where the story gets interesting.
Even after new Harvey Kneeslapper material stopped being produced regularly, his older sketches continued to appear in later Sesame Street episodes.
And decades later, Harvey actually returned.
In 2010, Harvey made a brief cameo in Episode 4209, performed by Matt Vogel.
Then came an even bigger surprise.
For Sesame Street’s 50th Anniversary Celebration in 2019, Harvey appeared again, this time performed by Eric Jacobson. The anniversary special brought back numerous classic and long-absent characters including Harvey, Don Music, Forgetful Jones, Sherlock Hemlock and Roosevelt Franklin.
Harvey even returned to his old routine.
Some things apparently never change.
Why Fans Still Remember Harvey Kneeslapper
Harvey was never Big Bird.
He wasn’t Cookie Monster, Grover or Oscar.
He didn’t need to be.
Characters like Harvey represent something special about early Sesame Street. The show could experiment with bizarre personalities, strange voices and incredibly simple comedy and see what stuck.
Some became television icons.
Others appeared for a few years and quietly vanished.
And sometimes those vanished characters become the ones longtime fans remember most fondly.
