Corrected entry: When John Candy gets hit in the nose with the golf ball, there is no blood, no bruising, nothing. His nose would have been broken by the speed that ball was going yet when you see him in the rest of the movie, his eyes are not blacked, he has no swelling and doesn't even seem to have been hit.
Corrected entry: When Roman is getting ready to leave with his family after he and Chet get into the argument, he tells Chet that he overheard him talking to "Kate and Connie's dad" in the john at their wedding, and he supposedly heard Chet call him a "crooked S.O.B." Later in the film, when Roman comes back to give Chet his check back (because he feels guilty), he says that he never heard Chet and his "brother" talking that night. Brother, not father as he said earlier in the film.
Corrected entry: When Buck is playing pool in the arcade with Ben he 'assaults' Cammie with his cue. She spins around flinging his cue across the room. The next shot she is staring him down as he is holding his cue again. (00:34:30)
