Apparantly, my uncle who is a big fan, was watching Des and Mel and Noel said he would stop a bus and say so and so is in here with an offer of £however much, deal or no deal?

That would be class!

I saw that interview as well, Noel said he loves the free reign that he's given to wonder anywhere around the studio while presenting the show. As you say he wants to go outside one day and stop a bus and jump on and ask people on there what the contestant should do

He says the studio is right on a busy road in Bristol so it would be easy to do. He has been interacting a lot more with the audience lately, so I could see him trying it

The one thing though is how long would it take, but it would be amazing TV

Each show recording is 90 minutes, cut down to 45 minutes transmitted. I would think it would be possible but I doubt the cameras would leave the studio so you'd have to bring the person into a TV studio (a bit like David Letterman's show).
