It might not count as I didn't win it, but I benefited from it. And it's palace-related, so...
In the 90s cable TV came to Croydon. Some might remember them digging up the pavements to lay the actual cables. Anyway, Palace started an in-house channel. It was incredibly ropey, all filmed on a camcorder or something. They used to give away prizes to try and build an audience for this new venture (remember, this is all pre internet, never mind club social media channels and so on).
Thing is, to begin with only a very small number of people paid for cable TV. Only a small proportion of them were palace supporters, and of those only a handful even knew when this wobbly bag of s***, amateur hour TV show was on, never mind were prepared to sit through it.
My mate, however, ticked all three boxes. For a short window of time there were about ten people phoning in to try and win about ten prizes every week. My mate won a replica top one week, a calendar the next, some other s*** after that.
One week he hit the jackpot, two tickets for the new executive boxes at the Whitehorse end.
And so it was that on Boxing day 1994 (I think) two spotty teenage oiks turned up and had an executive box to ourselves!
There was a fridge full of beer but we were too nervous to get stuck in, just in case it wasn't complementary!
