The hilarious story about the husband who f--ted every morning reminded me of when my husband's hair was turning white. He hated it and started dyeing. That's fine, but every Saturday morning he did it again! He was doing it so much his hair was turning purple! I told him he shouldn't do it so often; if he didn't stop it his hair would fall out. He didn't stop. So one morning while he was showering and I was making the bed, I cut off some "hair" from the fabric you use for dolls' hair, and sprinkled some over his pillow. Then I yelled in shock and said, "What's this all over your pillowcase?"
I let him figure it out for himself. The dyeing stopped, and he soon had beautiful silvery hair.
