Needs More Cowbell 

I was in my car driving this morning when I happened to hear "Don't Fear the Reaper" by Blue Oyster Cult. I can't listen to that song without laughing anymore. I kept picturing the classic SNL skit with Christopher Walken and Will Ferrell.

I've got a fever! And the only prescription... is more cowbell!

The other song that is permaently ruined for me is "Linger" by the Cranberries, which thanks to my brother-in-law Randy, I can't hear without thinking of him farting.

What favorite songs of yours have been ruined by people?
