[glatt]

In college, I found a plastic crystal beer mug somebody left at a dorm party. It was nice. I washed it and was bragging to my friends about my find. It said "unbreakable" right on it. I tossed it against the concrete block wall and it clattered to the tile floor, completely unharmed. I actually said that it was unbreakable.

My friend said "I can break it."

I told him to go ahead and try, confident that it wouldn't break. He stood in my doorway with the mug, and wound up like a pitcher in a baseball game, and threw it with all his might against the concrete block wall. And it broke.

I was both impressed and a little bummed.
