The Hole-in-the-Wall Gang - S4-E21
Other mistake: In the previous episode, when Jesse almost moved into Becky's apartment, Stephanie moved into Jesse's old room. Then it was decided that Jesse and Becky would turn the Tanner house attic into an apartment. However, Joey is now taking Jesse's old room, with no explanation. Stephanie has to share a room with DJ again. This does not make sense because, with Jesse living in the attic, his room would still be available for Stephanie.

Other mistake: It looks like she has earring holes. Didn't she get her ears pierced later on in the series?
