A man was annoyed when his wife told him that a car had backed into hers, damaging the front bumper, and that she hadn’t made a note of the licence plate number. “What kind of car was he driving?” asked the husband.

“I don’t know,” she said.

“I can never tell one make of car from another.” Hearing this, the husband decided it was time for her to learn and for the next few days, whenever they were out on the road, he made her name each car they passed until he was satisfied that she could identify every make. It worked. A week later, she bounded in with a big grin on her face. “Darling,” she said. “I hit a Pontiac G8!”
