One morning I was called to pick up my son at the school nurse's office.

When I walked through the main entrance, I noticed a woman, curlers in her hair, wearing pajamas. "Why are you dressed like that?" I asked her.

"I told my son," she explained, "that if he ever did anything to embarrass me, I would embarrass him back. He was caught cutting school. So now I've come to spend the day with him!"
