My two most embarrassing moments took place whilst I was in the BBs.
I once qualified to represent 1st Tulliallan at the summer West Fife Under-11 BB Athletic Finals (or whatever it was called) in the long jump. Qualifying took place in the BB hall in Kincardine, with the floor covered in matting and quilts, Nae bother.
However, the finals themselves took place at Pitreavie athletics stadium in Dunfermline. Hundreds of people were watching. In 3 attempts, I didn't even reach the sand-pit...
You'll have to buy me several pints before you get the other story out of me!
