I once won a bad beat jackpot at Cryptologic. My quad aces lost to a royal flush. Unfortunately, I "only" got about $1.4k for it (At that point the jackpot was about 3k, they split it something like 50% for the loser, 25% for the winner and the rest is shared among the other guys who played the hand) - woulda been lots more but I think a JP had been won earlier that day or something so it was quite low (Crypto resets it back to 1k after each win).
Here's the crazy thing though - I DIDN'T GO BROKE ON THE HAND ...
