Take My Sister, Please - S5-E3
Continuity mistake: When DJ is giving her presentation to the guys about letting her have her own room, she brings up a point that Stephanie and Michelle are now the same age as DJ and Stephanie were when they started sharing a room. But Stephanie was 5 and DJ was 10 when the show started and they began sharing a room. In this episode, Stephanie was about 9 and Michelle hadn't turned 5 quite yet.
Character mistake: Danny and Joey finds out that their high school girlfriend was using them to make Jesse jealous. In season 1 it states that Danny is 30, and Jesse is 23, making Jesse 7 years younger. High School Danny would be 16-18, making Jesse 9-11 years old, and not in High School.
Answer: No.
