Mr. Derp

Mr. Derp replaced Chef for a short time in "The Succubus", telling the boys Chef quit due to marriage. He wears an apron which reads, "come an' get it!" Mr. Derp is into Slapstick humor, which is painful, physical humor. His name, according to the commentary on the episode, comes from a word invented by Trey Parker and Matt Stone themselves, which they say means "an obvious joke" or is said when they do something dumb. Mr. Derp also made a brief cameo in "Timmy 2000" as the man in charge of the lemonade stand at the concert, and in the foreground at the adventure park in &quot;Professor Chaos".

After Chef's demise he may be his replacement as he was seen in the background in "Eek, a Penis!", and running out of the school in "Cartoon Wars Part I". However, Randy Marsh was seen as the school chef in "Crème Fraiche".
