Corrected entry: As the announcements are made, a bundle of dynamite is thrown through the window. The fuse is half way burned when the man says "and duck!" When he ducks, the explosion occurs, but the fuse couldn't have burned that fast.

Correction: Given this film's parodic and absurdist nature, this very likely was intentional.
