Not really a bad purchase per se, but when I was really little, maybe 5 or 6, my dad ran a Cajun restaurant and we had crawfish shipped in regularly. Whenever he found a cool looking one he would give it to me, so at one point I had maybe 8 bowls and various containers with neat crays. White, purple, blue, you name it I had one. Eventually they all died off but one, and around the same time I got a goldfish at a carnival and we had it in a bowl. One day when I was at school my mom decided to consolidate the bowls, thinking the goldfish would be safe because it was almost as big as the cray... We came home to find the cray munching on the goldfish like a sandwich. I wasn't so much sad as angry at my mom - we got feeder fish weekly to feed the crawfish!
