"Risk it for a biscuit"

Back to the good old days of Nile fm radio station and to be more clear to the big drive home show ohh.. memories can flood for years with that station and its shows, i remembered there used to be a really big competetion on the "Big drive home" it was called risk it for a biscuit -which is cadbury biscuit chocolate - and i can't really remember what it was all about but this name really got through my mind right now those 5 simple words "Risk it for a biscuit"

Cause these days i really feel i won't get any biscuits in my life unless i risk it .. and am left with the thought that i really need to "Risk it for a biscuit".
