My Sis and her g/f won a weeks cyclicng holiday in Menorca (or similar) at the Tour de Manchester a couple of years back. They didn't do any cycling and almost got hit by the water bottle from a competitor from some race that was taking place on the island. My Sister picked up the bottle and launched it after the chap on the bike shouting "Oi, watch it!" (bu probably less politely)... I pointed out that she could probably have sold it on
eBay if she'd known who threw it!
I won an LCD TV when we had a Bike-to-Work / Computers for work scheme type roadshow/info event some years ago at work. I only went over to accompany my two office colleagues... and won. They were distinctly unimpressed!!
