Worst & Funniest Songs to Teach

I would like to know what some of the worst and/or funniest songs were that people have requested to learn.

I'm a 32-year-old man and I've had to teach a lot of Taylor Swift, Jonas Brothers, and even some High School Musical. But that stuff isn't too bad. It comes with the territory...

I did have a young boy tell be that he wanted to learn anything by the B52s, which I thought was a little strange. I also had a kid ask me teach him the theme song to Spaceballs, which was understandable because it was his favorite movie, but the theme is very orchestral and not something that easily translates to a simple guitar part.
