The lions tour in Australia few years back, and they were leading half time easily and I said if they lose from here I will have a skinhead, 2 hrs later I'm in the barbers! My young daughter wouldnt come near me for weeks afterwards cos she was scared.
I have also won a car in a bet. My mate left his car outside the pub for 6 weeks and I said you should move that car its an eyesore, to which he replied good car that, never fails to start blah blah. I said it wouldnt start so he said if it dont start 1st time I can have it. Out we goes, he turns it over and nothing. Some youngsters had pinched the battery
It was a Nissan Primera not great but alright for f**k all
