Ho ho..

Little boy asks his father, a mathematician, "What's two plus two?"
Dad, "Two plus two is four, of course."

He goes to his mom, a shrink, and asks, "Mom, what's two plus two?"
Mom: "Well, that answer would be affected by perception and cultural conditioning, it could be four...or it could be twenty-two."

Dissatisfied, he goes to his uncle, an attorney, and asks, "What's two plus two?"
His uncle asks, "How much do you want it to be?"
