When I was a kid, my friend and I were foolishly playing catch with a football inside his house. One of the passes hit the suspended ceiling in the room and caused the entire thing to collapse on our heads.

The tiles and metal suspension rods are very light so no injuries. But since his parents were out of the house, we frantically scrambled to put it all back up before his parents got home, so as not to get in a ton of trouble.

We had quite a laugh about it several years later.
