Run Over By Mother-In-Law

RUN OVER BY MOTHER-IN-LAW
The hit-and-run victim was just getting to his feet when a policeman ran up to help.
"My mother-in-law just tried to run over me!" the shaken man told the cop.
"The car hit you from behind," the officer said. "How could you tell it was your mother-in-law?"
"I recognized her laugh!"
