This is probably one of the funniest moments of any sitcom I have ever seen. Its from the show News Radio. Here, the owner of the radio station, Jimmy James, is about to give a reading of his autobiography; however, this is an English translation of the Japanese translation of the book. Apparently, the original didn't do so well here, but when the Japanese translation did well, they decided to translate that version back into English.
Here's the clip. Enjoy!
