Continuity: The beer that the guys make from the stolen recipe is a reddish-brown color. When the Wolfhouse brothers begin to bottle and sell the beer, the beer is in light green bottles. The beer inside the bottle is not reddish-brown, or else the bottles would have looked darker when full. The unopened bottles look like there's a light-colored beer inside of them.

Continuity: 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.

Other: In the beginning of the movie, when Jan and Todd watch Ireland go against Germany, the scoreboard reads 2-2 for the "Boot Line Chug," implying a best-of-five bracket. However, when the Americans compete, it is merely the "Line Chug" sudden death in a best of seven event.

Continuity: 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.
