Mr. and Mrs. Smith were always fighting. Then one morning as Mrs. Smith was driving around town, running some errands, her car was crashed into by a hit and run driver at a relatively low speed.

A police officer rushed up and asked her if she'd taken the car's number.

"I didn't need to," replied Mrs. Smith. "It was my husband in that car."

"Did you see him?" asked the officer.

"No," said Mrs. Smith, "but I'd recognize that laugh anywhere."
