Invader Zim Episode 21 - FBI Warning of Doom Episode Title:FBI Warning of Doom.Episode Description:GIR is watching a rented movie and Zim sees the FBI piracy warning on it (Note that, instead of listing the usual consequences usually seen in FBI warnings, it says something along the lines of, "or else we'll hunt you down like the dirty monkey you are and force you to ride a greased piggy while wearing a moose skin and singing folk tunes"). The rental store calls to demand that the movie be returned as it is very over due, but Zim fears that his mission is threatened unless he returns the movie immediately. (The computer, forced to make up FBI facts, gives Zim the wrong idea about what the FBI is. This really scares Zim.) He returns to the mall and breaks in so he can return the disc into the return slot, but mall security discovers him and so he battles through to get the DVD returned.
