Michelle Rides Again (2) - S8-E24
Continuity mistake: In the scene where the twins take Michelle's Rigby doll, as they walk towards a dresser the boy with the doll holds it with both hands. Then in the next cut when the boy says "She didn't say that", you can see he is now holding the doll under his arm.
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.
