 During the ending credits, "outtakes" are seen. All these "outtakes" are  spoofs of outtakes from Jackie Chan movies. For example, after each  "injury" four Asian men in red jumpsuits run out to help the "injured"  (similar to many Jackie Chan movies,) and the "outtake" ends with the  "injured" person giving a thumbs up to the camera while on a stretcher (a  la Jackie Chan.)
