Barber, barber shave a pig
How many hairs to make a wig?
Four and twenty, that's enough
To give the barber a pinch of snuff

Barber you think you're doin' fine
[From: http://www.elyrics.net ]
But you'd better think twice before you touch that swine
'Cause if you were the pig and the pig were you
She might just wanna make barber stew!
