Audio problem: When Knox shouts "You blind as a horse's ass" later on in the movie, his lip movements don't match with what he's saying.
Continuity mistake: When JP squirts the mustard onto Knox's assistant, the pattern changes during the scene.
Continuity mistake: The stain on David's butt from the nachos is gone when he goes to get coffee.
Factual error: Roger's dad says when the "Angels win the pennant." During the last final scene/regular season game, after the win, Ranch Wilder announces that "the Angels won the pennant." They would have to have won the American League Championship Series in order to win the pennant.
Character mistake: The batter hit a line drive hit over the second baseman Garcia's head. The pitcher Bass whips his head to his left as the ball goes to right or right center field. The announcer said there's a base hit to left field when it was right field.
Answer: "Keep your nose clean" just means stay out of trouble.
