I'm the kind of guy who likes to throw things across the room into wastebaskets, so when I changed a light bulb in the bathroom, the empty wastebasket beckoned. Not that I would do anything so crazy as try to score two points across the room; I just stood next to the basket and dropped the bulb into it.
The wastebasket was made of plastic. What could go wrong?
Well I'll tell you what could go wrong.
The bulb landed on the bottom of the basket, bounced gracefully up and over the side, and smashed to bits on the tile floor. That's what could go wrong.
