The Wedding of Bobby Hill - S3-E14
Question: When Luanne tells Bobby that he wasn't in Rad's inner circle and he was just a hanger-on, what does she mean when she says "like AJ"?
Answer: This is a reference to the Backstreet Boys, of whom AJ was the least popular member.
Has nothing to do with AJ from BSB. He was never the least popular. He was like the main singer in the group. Howie was the least favorite and didn't even sing.
Answer: We're never told, but he was just a friend of Rad.
Answer: I just watched this episode on Hulu yesterday. There is a moment in the hotel (where Rad takes Luanne for a date) when Rad says hello to a man named AJ, while he hugs Luanne. I am quite sure that I never saw this moment when the episode aired on regular TV channels.
