Somebody thought it would be funny to put a "For Sale" sign on the high school I went to when I was a senior. It got a good laugh that morning. However, someone thought it would be even funnier to put the sign on a teacher's car, and they did...on our home room teacher's car. That teacher was also the home ec teacher, and she got a little unhinged by the whole incident. She had a nervous breakdown from it, quoting that it wasn't a prank, but "destruction of her personal property" (yes, placing a SIGN on the windshielf of her car). She freaked, whipped herself into a frenzy, and had a few days off as she collected herself...like I said, a breakdown.
