For the past five decades, Sesame Street has been providing children across the world with wholesome, educational television programming. However, that doesn't mean things don't occasionally get a little NSFW behind the scenes.

Case in point: a clip of Seinfeld star Julia Louis-Dreyfus cursing in a Sesame Street outtake, much to the amusement of Elmo and Zoe.

"Shit!" Louis-Dreyfus exclaims when she forgets a line. Nevertheless, Elmo and Zoe remain in-character, pointing out that Louis-Dreyfus said a bad word and demanding she put $5 in the proverbial swear jar.

This isn't the first instance of foul language on the titular Sesame Street. In fact, in December, a clip began circulating in which is sounded as though Grover dropped an F-bomb, although it was merely an auditory illusion.

Sesame Street premiered in 1969 as a sketch comedy, animation and puppetry kids show, originally produced by the Sesame Workshop, and many of its characters were created using Jim Henson's Muppets. After airing on PBS, Sesame Street moved its first-run episodes to HBO in 2016, where they remain today.

The show's biggest move will be on January 15, 2021, when Sesame Street heads to the big screen in a film directed by Jonathan Krisel and starring Anne Hathaway.
