First of all, when they are at the airport and Chris Farley makes a phone call to Michelle (was that her name? I can't believe I forgot) back in Sandusky, he gets her answering machine and starts to leave a message. Then, the camera changes to David Spades situation, and then back to Chris Farley, who is still leaving a message on her answering machine, yet asks, "So, I'll talk to you later?" Maybe that's not really a slip-up. The other one is when Chris Farley is in the airplane bathroom and his tie becomes stuck in the toilet. When he finally jerks himself loose, because of the layout of the bathroom and position of the door, he should not fly out the door but rather into one of the walls. This obviously does not happen as he breaks the door down and falls into the aisle of the airplane.
