For his birthday a boy asks for a bicycle.
His father says, "Son, we'd give you one, but the mortgage on this house is $280,000. There's no way we can afford it."
The next day the father sees the boy heading out the front door carrying a suitcase. So he asks, "Son, what are you doing?"
The boy says, "I was walking past your room last night and heard you telling mommy you were pulling out. Then I heard her tell you to wait because she was coming, too. And I'll be damned if I'm staying here by myself with a $280,000 mortgage and no bike!"
