I have just been spending a ridiculous amount of time laughing at the misheard lyrics on this site. I suppose I am very geeky, but some of them are downright hilarious. For instance:

R.E.M "Everybody Hurts":
"Don't throw your ham"

Biffy Clyro "The Kids From Kibble..."
"Do you believe in eye care?"

Queens Of The Stone Age "The Lost Art Of Keeping A Secret":
"Whatever you do/don't tell on your mom"

Radiohead "Bones"
"I used to fly like a pizza pan"

As I said, juvenile, but very funny. I guess I should call this an opportunity to make this a favourite misherd lyrics thread.
