From Amy - best short joke of 2007

For his birthday, little Joe asked for a 10-speed bicycle. His father said, "Son, we'd give you one, but the mortgage on this house is $280,000 & your mother just lost her job. There's no way we can afford it."

The next day the father saw little Joe heading out the front door with a suitcase. So he asked, "Son, where are you going?" Little Joe told him; "I was walking past your room last night and heard you telling Mom 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 & no bike!
