One night, a lady stumbled into the police station with a black eye. She claimed she heard a noise in her back yard and went to investigate. The next thing she knew, she was hit in the eye and knocked out cold.
An officer was sent to her house to investigate, and he returned 1-1/2 hours later with a black eye.
"Did you get hit by the same person?" his captain asked.
"No," he replied. "I stepped on the same rake."
