I have a story vaguely like Asherdan's. On my second trip to Vegas, we went to the Rio relatively early Saturday morning in order to meet friends for brunch. We had some time to kill, so I played some blackjack. I was betting progressively--$5 first, then every time I won I added $5 to the bet, but if I lost I started back at $5. (I realize this makes no difference in the long run, but it's fun sometimes.) At one point I won or pushed on something like 12 hands in a row, so by the end of the session I was up $200. Combined with the $100 I had won the night before, I was rollin'. (At this point in my life, $300 was a TREMENDOUS sum of money.)
I also drank a lot of toasted almonds during that session. When the rest of the crew showed up, I gave my roommate the $100 I owed him (as a $100 bill), and said "No matter what happens the rest of this trip, do NOT give this back to me. We're even."
After brunch I paid for everyone to go on one of those eight-seat auto-racing games in the arcade where you all race simultaneously, and I proved once and for all that you should not drink and drive.
