Continuity mistake: When Cory first confronts Shawn over kissing Topanga in their dorm room, Shawn is looking through his drawer for a shirt. The shot goes to Cory for a second, then when it goes back to Shawn he's had time to find a shirt and put it on - the shot wasn't off him for nearly enough time to do that.
Continuity mistake: Just after Cory talks about being a "baby shower machine", Morgan walks past him. There's then a quick shot of Alan and then we see Cory again, and again Morgan walks past him. It's not the same shot from two different angles, as Cory is acting differently each time.

Continuity mistake: When Cory, Shawn and Feeny are at the table, Feeny's glass is almost half full. Cory later fills it up, but in the next shot the glass is half full again. In a later shot it's full and then it's somewhere in between half full and filled up.
