The Importance of Being Phoebe - S5-E11
Continuity mistake: When Phoebe is lying on the ground and is supposed to be unconscious, when Cole goes to pick her up you can see Phoebe throw her arms around his neck. (00:29:15)
The Importance of Not Being Too Earnest - S6-E3
Continuity mistake: When Joey accesses her email address book to send an email to Dawson, she inadvertently hits the address above his, sending her email to the entire Worthington campus. Dawson's email address in Joey's address book is DawsonLeery@worthington.edu. Dawson does not go to Worthington and would not have a campus email account.
Continuity mistake: Onizuka is on his bike with Mizuki after she utterly murdered the sushi plate. He is still reminiscing about the sweet prime cut tuna while he is at the traffic lights. Several people cross the street; there is a family with a little kid, and a guy in a denim jacket. In the wide shot it's clear that the family is to the guy's left, but in the tighter angle the guy passes them by on the opposite side. (00:34:00)
