I loved Superstars back in the day, but one thing irked me. As far as I cam remember, participants were not allowed to compete in their own sports; but there was one guy (David Emery?) - who was a steeple chaser and, for some unknown reason, he was given a dispensation so he could participate in the chase. He had to start 100m back or something, but he always won.
Never got my head around why he was allowed that - maybe someone can enlighten me ...
