I hated UHF as a kid. HATED it. I liked Wierd Al songs growing up, my older brother was an early adopter of the Nerd Kings music; but when my 10 year old self watched that movie I was just annoyed. Wheel of Fish? Just gross and stupid. Kramer's character was just irritating. I was angry that they did the firehouse thing to some poor unsuspecting kid. And also for the record: we had a kids show in AZ at the time called Wallace and Ladmo; to me, it was like an evil version of their show (it was nowhere near as bonkers but I was a kid), and I loved that show; even got on for a Ladmo Bag bc of my older bro. Kind of felt like they were picking on them; which they weren't, but again, I was 10. I've honestly never been able to bring myself to watch it again, because it's ingrained as being so dorky, over the top and annoying I just can't do it.
And one last thing: let's not act like Wierd Al was cool, the kids I knew that listened to him were all dorks like me. I just don't buy it when people claimed they liked him as kids. Maybe he became ironically hip after Amish Paradise, but from 1980s up to early 90s, he was 100% nerd. No chic.
