At the main menu (Single Player/Multiplayer/Options/...), type:
kratin'it: Plays a movie
goofy: Changes the picture for Wacky World in the Select Level screen
followme: Select Credits after typing "followme" to reach a joke version of the credits and two small additional secret levels. (Note that you can then use the usual cheat codes to jump to these levels.) [thanks to Hugo Janacek for this one]

While playing, press Esc then type:
1werdna, 2werdna, 3werdna, or knuckleheads: Changes the background art
