OK, it is the episode where Joey is all upset about college. She goes to a party with Pacey and gets drunk. This is Joey's drunk episode! Anyway,she goes to a party at..I forget his name? The guy who always bothers Joey. He knew Jen from their other school. Know who I mean? Anyway, Joey, Pacey (and mostly everyone else) goes to that guy's house for a party. In this episode Jack has fractured his arm. In his other hand he's holding a drink. The camera pans away to someone else, then back to him and just one time the sling is on the opposite arm!! Good luck seeing this if you have a copy of this episode. When you do notice it is blatantly obvious!!
