A couple months back, I was doing one of my regular weekend drives, and I caught an episode of Randy's Vinyl Tap on CBC radio. Great show, hosted by Randy Bachman, where he is providing his insights and commentaries on assorted music past and present. The topic of the specific show was Mondegreens. A Mondegreen is lyrics of a song that we mishear. There were a lot of funny ones, listen to podcast.
If you want a couple hours of good music and great musical insight you should also just listen to the program.
