Posh takes her car into a garage to have some dents removed. The
mechanic knowing she isn't the brightest Spice Girl in the world,
decides to play a joke on her. "You don't need me to take those dents
out," he says. "Just blow up the exhaust pipe and the metal
will pop back into place". So she takes the car home and tries it.
David spots her from the house, opens a window and shouts "You silly
cow! You have to wind the windows up first!"
