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: At the end of the movie when Tony Danza is pitching to the last batter, the batter hits a ball that is very low to the ground, and it appears as if it is going toward either shortstop or center field. But the announcer and camera shots indicate that it is headed toward the left field foul pole, and eventually going foul. How could it change directions like that?
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.
Other mistake: In the championship game at the end, Ray Mitchell hits a two run homer to tie the game. As Mitchell is crossing home, he never touches the plate.
Continuity mistake: Throughout the movie, the angels used two different stadiums. They used the Big A (as that is what it was called in 1994), then they also used the Oakland Coliseum as well.
Answer: "Keep your nose clean" just means stay out of trouble.
