Watch Sarah Silverman, Stephen Colbert Recite Kids' Bad Jokes

Comedian also reveals story behind boyfriend's penis nickname "the Great Christine Baranski" on 'Late Show'

Sarah Silverman is known for her acerbic, explicit sense of humor, but on Late Show With Stephen Colbert Tuesday, the comedian produced a different sort of comedy: Reciting unfunny jokes written by children. Colbert told Silverman that one of his favorite sites is a Tumblr called "Bad Kids Jokes," and the two then proceeded to read some of Colbert's nonsensical favorites.

"There were three guys on a plane. One bit into an apple, thought it was too sweet, and threw it out the window. The second guy bit into a rock," Silverman read. "That's the whole thing. That's terrible. Not funny." Colbert managed to dig up one depressing joke – "What do you call a middle-aged, sad, gray-haired woman? A teacher" – before Silverman closed out the bit with the classic "What did the egg say to the other egg? Have an egg-cellent day."

The interview also allowed Silverman to dip into her raunchy side, which she did with an anecdote about how she accidentally nicknamed her boyfriend's penis. Silverman, who's dating her Masters of Sex co-star Michael Sheen, jokingly tweeted that her boyfriend gave his penis the moniker "the great Christine Baranski." However, some celebrity outlets later published a blurb about how Sheen refers to his penis as "the great Christine Baranski."

After initially being upset with Silverman over the joke, Sheen told his girlfriend, "I played Henry the Fifth!" To which Colbert replied, "That would be an excellent name for his penis."
