I worked hard every day of my life
I worked till I ate my balls

The story:

I had the song on tape and went over this part dozens of times but couldn't hear it any other way. Finally I looked up the lyrics in a large number of different places and got the real ones. I still like telling the story and making jokes about it: "Been working a *little* too hard there, Freddy? Well, you know how the old saying goes: All work and no play makes Freddy Mercury eat his own balls."
