Standing at the edge of the lake, a man saw his wife flailing about in the deep water. Unable to swim, the man started to scream for help. A trout fisherman ran up.

The man said, My wife is drowning and I cant swim. Please save her. Ill give you a hundred dollars.

The fisherman dove into the water. In ten powerful strokes, he reached the woman, put his arm around her, and swam back to shore. Depositing her at the feet of the man, the fisherman said, Okay, wheres my hundred?

The man said, Look, when I saw her going down for the third time, I thought it was my wife. But this is my mother-in-law.

The fisherman reached into his pocket and said, Just my luck. How much do I owe you?
