High Anxiety - S7-E7
Revealing mistake: In the scene where Denise, Derek and Michelle are throwing the frisbee, when Derek catches the frisbee, he quickly looks up at the top of the fence and his arm is way too far up to have the frisbee get to Michelle. It is very interesting that the frisbee just happens to land on top of the fence.
Chosen answer: The first time was in the first season, episode 19 "The Seven-Month Itch", the second was in the fourth season, episode 1 "Greek Week", the third time was in the fifth season, episode 19 "The Devil Made Me Do It" and finally in the very last episode of the series, "Michelle Rides Again", season 8 episode 23.
