Some smart man once said that on the most exalted throne in the world, we are seated on nothing but our own arse.

Man who invented the hamburger was smart; man who invented the cheeseburger was a genius.

A smart man only believes half of what he hears, a wise man knows which half.

You're not too smart, are you? I like that in a man.

A smart man makes a mistake, learns from it, and never makes that mistake again. But a wise man finds a smart man and learns from him how to avoid the mistake altogether.

I'm a meathead. I can't help it, man. You've got smart people and you've got dumb people.
