"What's the use of my balls?"

The story:

This was just last week, when a moths flew in my house and I got into a discussion about whether all moths eat clothes and how come you never see mothballs any more. Then a couple days later I played the song and I was like, "Oh, duh! Mothballs! Mothballs, you idiot! Little tiny mothballs!"

But you gotta cut me some slack, the version I misheard was a cover by Joan Jett and Paul Westerberg. You'd totally believe Paul Westerberg was shouting about his balls, right?
