Revealing mistake: When Eric picks up Cory to show him the "For He's A Jolly Good Fellow" dance, Cory screams that Eric is going to knock over the candles, upon which one of the candles on the desk is knocked over and sets fire to the curtains.

Continuity mistake: When Morgan is telling Topanga that she wouldn't use her bridesmaid's dress to wipe her ass, she gets cut off by Alan who covers her mouth with his left hand and then begins dragging her out of the reception hall. When the shot changes, he is covering her mouth with his right hand. (00:17:22)
