A brain walks into a bar and says, "I'll have a pint of beer please."

The barman looks at him and says "Sorry, I can't serve you."

"Why not?" asks the brain.

"You're already out of your head."



A number twelve walks into a bar and asks the barman for a pint of beer.

"Sorry I can't serve you," states the barman.

"Why not?!" asks the number twelve with anger showing in its voice.

"You're under 18," replies the barman.
