Radio Days - S6-E4
Plot hole: At the end of Joey and Jesse's radio interview, the host Julie says "Joey Gladstone." However this appears to be the first time she's met him and when Jesse introduced him to her a few minutes before (in real time), he referred to him only as "Joey" and never once told her his surname nor is it mentioned in the interview. Furthermore, she also said she wasn't aware of The Ranger Joe Show so it doesn't make sense for her to suddenly know his last name minutes later when she was never told it previously.
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.
