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.
