A man is in his front yard attempting to fly a kite with his son. Every time the kite gets up into the air, it comes crashing down.
This goes on for a while when his wife sticks her head out of the front door and yells, "You need more tail."
The father turns to his son and says, "Son, I'll never understand your mother. I told her yesterday I needed more tail, and she told me to go fly a kite.
