My wife told me about this some years ago. I said Bull Scrap! I did a little "Frankenstein" with the freezer to prove her wrong.
I put 18 small Jimmies in for 24 hours in a brown bag. well I got them out and let them sit a few hours in the big pot. When I called the wife to come see they all looked as dead as a road killed rabbit. She starts getting them out of the pot one by one. When she was done she had 15 dead ones in a pile, and three live ones trying like [Sam Hill] to run away from her. Its true I guess. Yes I washed they all up and had steamed crabs for breakfast.
