Revealing mistake: When Louis plays his hand of blackjack on the cruise, he gets a double split with all 8s, and the second cards he gets dealt are all 3s, but two of them are the 3 of hearts. There are not two 3 of hearts in a deck of cards.

Factual error: When Luis is in the video store, they pan out to show the video rack he was looking at. They show Disney's Tarzan on one of the racks. Being that this show is set between 1995-1998 for all 4 of the seasons, Tarzan should not be on the shelf as it was not out until 1999.
