/me slaps you around with a large trout
WHY WOULD ANYONE THINK OF SLAPPING ME WITH A FISH?!
I think it originated on the Woody Woodpecker show in the Chilly Willy bit where characters often slapped each other with fish. I also vaguely remember Warner Brothers characters doing this act every once in a while.
Another theory brought up by fellow noders is that it comes from Monty Python’s The Fish Slapping Dance.
