I once gambled for Pizza at Smokin Cue in Charlotte. I was giving up the three out and the breaks. I lost four pizzas and then played the last double or nothing but took away a ball so I wasn't giving up a corner ball. I won that set hill hill.
I have gambled for dinner, breakfast, hookers (just kidding), chores, situps/pushups, clothes, cars, cues, stupid human tricks, and I am sure other silly things that don't pop into my head right now.
What I thought of when I saw your post was a reality show where the pool players had to gamble for food. Steak if you win - bread and water if you lose. That might be cool. Until you saw the players cutting up the steak afterwards.........ba dum dum ;-)
