They're not as good as these balls:

My balls are always bouncing
And my balls are always bouncing
My ballroom always full
And everybody comes and comes again
If your name is on the guest list
No one can take you higher
Everybody says I've got
Great balls of fire

[Chorus]
I've got big balls
I've got big balls
They're such big balls
And they're dirty big balls
And he's got big balls
And she's got big balls
(But we've got the biggest balls of them all)

Thankx, AC/DC, you guys indeed have the biggest balls of all!
