Fun casino donkey story from me:
I was playing 3/6 with a kill to 6/12 Omaha/8 at the Majestic Star in IN a couple weekends ago and a guy sat down to play and proceded to:
*Try to buy in from the table only to learn that the first buy-in had to be made from the cage
*Have O8 explained to him by the guy on his right (who at this point was a known average O8 donkey)
*Take his first 4 cards and pull them off the table into his chest and then hold them on his lap (he pulled them off about 50% of the time for the first 10 hands before figuring out how to keep them on the table)
*Limped into the first couple of hands
At this point I could have used a napkin or a rag to clean up the slobber on the table from my drooling waiting to get this guy's money. My buddy was sitting on my left and I came up with a prop bet for him. The new guy bought in for $100 and I bet my buddy $5 that he'd be busted before the button got to him the 3rd time (basically within ~22 hands).
After one go around the table he had made it to showdown all but 1 or 2 times, hadn't one a hand, and was under $40. When he was almost at the felt and had ~$20, I had a hand that raised PF and my buddy re-raised on my left for the sole purpose to drive out the donkey (classic!). Unfortunately for my buddy he called, but more unfortunately for me he ended up all-in and caught half the pot so was back up to ~$40.
The guy rebought eventually but we kept the spirit of the bet to be when he lost his original $100. With 2 more hands before the button hit him he was down to under $10 on his original bet. Sure enough, he limps, gets 5-way action, check/calls all the way to the river, & scoops a ~$60 pot

I lost my side bet, but the guy ended up donking out the $160 he bought in. I wasn't able to get as much as I hoped but at least he was giving it to other people at the table that I knew I could beat.
I think this will become a tradition for me though --- it's a blast to lay a bet that someone's going to lose 1/2BB+ PER HAND and then watch as it happens.
