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.
Other mistake: Near the end of the film when they have the 5 boot drink off, at times the boots is at such an angle that normally beer would spill out, if any was actually in it. Plus every time they put down the boot the areas around their mouths are dry, which should have been soaking wet.
