I was in a Casino with my mate (Im not a gambler) and he was on the roulette with one chip left, don't remember the value of it and I said 'stick it on 19' - he did and it came up!
We had slap up tea at Mrs Miggins Pie Shop/Got a Kebab that night!
Completely OT but related to this gem. Was at a Casino with a friend on those electric machines. He was down to his last tenner and was tapping the screen. Just before the spin he accidentally stuck his remaining money on a single number. The bigger came in. Jammy git.
