When I was a teen still livin' at home, I would go out and flyfish for Bluegills at the lake in the spring when they were on their beds. I would freeze them by the bucket full. One hot July day when my parents were gone on vacation, I left three 5 gallon buckets of frozen bluegills out on the back porch to "ripen". Well, It got busy at work and I kinda forgot about them for a "few" days. I was workin' nights at the time. The afternoon my parents came home there was hell to pay and my Dad demanded that I get rid of them right away. Well, you guessed it one of the buckets tipped over in the back of my toyota corolla and that car never smelled the same again...ever.
Fish works though, the smellier the better.
