Standing at the edge of the lake, a
man saw
a woman flailing about in the deep water. Unable to swim, the
man
screamed for help. A trout fisherman ran up. The man said, “My wife

is drowning and I can’t swim. Please save her. I’ll 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,
where’s my hundred dollars?” 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?”
