Continuity mistake: When Fink is explaining the difficulty of the boot on the chalk board, he draws one circle on the toe of the drawing, it then changes to two after he throws Bo Bo and says "Sorry" and changes back to one circle again. You can tell that they are two different drawings altogether.
Continuity mistake: When Landfill tries to drink his way out of the tank, he drinks a lot of the beer to make the top fall, when the other guy comes in and finds him dead the top of the beer ends higher.
Question: In the end Fink finally figures out the trick to the boot. How come the Germans don't use this trick, but drink the boot straightforward instead of spinning it like the Americans do?
