My quiz mates and I once successfully got through an audition for Eggheads, but most of the production staff got the push soon after and our records and contact details went with them. Never made it to the show, but the audition was a riot.
We hadn't appreciated that we needed a sixth team member to act as a reserve, so at the very last minute I called in a favour from my mate Simon. Simon had never watched Eggheads, and had no idea what he was letting himself in for. When they started the screen test by asking us to introduce ourselves, things went fine. Then they went round us in turn asking us questions about the Eggheads, such as which one you would like to go to dinner with, which ones you reckon you could beat etc. Simon was nervous. His last words prior to entering the filming room were "Who the f*** is this CJ anyway?" and they asked him about CJ De Mooiy!! He had also been unwell quite recently, and it was very hot in there. I was seated in the front row, as were two of my team mates. Simon was one of three having to stand up behind us. Half way through answering that question, the back of my chair started shuddering, Simon went quiet and we heard a thud behind us. When I turned around, there was no sign of him. Until we looked on the floor. My mates now refer to him as "Simon the Incredible Fainting Man". We got the film crew to let us watch it back in slow motion. Epic way of avoiding a question!
I also went to an audition for Pointless with my mate Andy. We did quite well, but it was quite obvious who the successful pairs were going to be, as 8/10 contestants were, like us, your typical balding, middle-aged, white men. They went for the characterful father and son combo and the sugar daddy and bubbly blonde thicko who scored 100 on every question she answered. They do have to have a diverse bunch of contestants for each show I suppose.
