My best accident that gave a good result in gambling was on a poker game. I hit all in button accidentally while I had a hand of 2 and 3, there were 4 players call my all in and they had better cards than mine but fortunately I won the game with a four of a kind (3). It was happened on a fiat poker game though but I won decent amount of money at that time.
If this really happened and if it would be clipped in a YouTube video, you'd make some extra cash from YouTube as well!
I would like to see the others' reactions!
