[XIII]

Years ago they used to operate waiting lists for quiz shows such was demand for some of them, due to limited opportunity to get on the show itself.  Bullseye used to have a massive waiting list just to sit in the audience never mind play the main game such was its popularity and one of the Chasers told some red top tabloid rag somewhere that there is at least a three year waiting list to get on The Chase.

I'm not sure if a waitlist actually exists for something like The Chase, they get a lot of applications a year though.
