A Guy Is Sitting At A Bar Drinking A Pint Of Lager.

While he's sitting there, he notices the barman's cat up on the bar, one leg in the air, licking its balls.

The guy turns to the barman and remarks "Fuck. I wish I could do that. It'd be so relaxing..."

"You can do it, " replies the barman. "Just give him a saucer of milk and I'm sure he'd let you!"
