I did have a similar story where the guy wouldn't play me so I threw $5 and only used the rubber bumper on the butt of the cue, don't know how but I beat him lolAlthough it was technically not a cue but I once played a game for $20 using a branch that an old guy used as a walking stick. The branch was about four feet long and two inches around on the bottom. The stick was about 1/2 inch around on the end that would be put on the ground when walking. I used the narrow end to hit the cue ball but there was about a 40 degree bend to it two inches down from the tip that had been mushroomed out from grinding on the ground.
The guy that I was betting, was the worst player I think I have ever played. Due to the dog leg where my bridge hand was it was impossible to stroke the cue and most my attempts resulted in miscues. The game lasted nearly 45 minutes and I eventually made the 8 ball and won. A game and a cue I will never forget.
