Other mistake: 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.
Suggested correction: The rules simply changed in the year between the 2 beerfests. The MLB World Series used to be best of 5 but was changed to best of 7 in 1985.
