Continuity mistake: In episode 10 (Joey's Place) the Tanner family move Joey into the garage, redecorating it so the entire place is filled with Joey's furniture, but in this episode it shows the characters in and out of the garage which is completely empty and back the way it was before Joey moved in. Later in the episode Joey's stuff is out of the alcove again.
In a Class of Their Own - S15-E4
Continuity mistake: When Paul tears up the list and starts typing his own list, he says "If Barry's on the list, then I'm gonna be on the list as well." However, when the video footage from Barry's camcorder is later shown on the TV in the assembly hall, in the recorded footage Paul now says "If Barry's on the list, then I'm gonna be as well."
