Why do so many people think the arrival of summer means it's time to pack away all the clothes that actually fit them? That it's time to reveal their out-of-shape bodies by wearing Speedos and tube tops?On that show "Cops," every time they show up to arrest some guy, he answers the door (or climbs out the back window) shirtless. It's as if shirts hurt criminals the way Kryptonite hurts Superman.
