Best start to a Wednesday for some time

So I've just come out of swimming, and I'm wandering down Tottenham Court Road towards work. I notice, coming in the other direction, a man wearing a sandwich board, and he has a proper full-on TV camera trained on him, as he ambles nonchalantly down the street. Curious, I turn my attention to his board. It says this:

"If you ask me for a £5 note, you can have one."

So I did.

"Excuse me, could I have a £5 note, please?"
"Sure! Here you go. Have a nice day."
"Thanks very much - you too!"

And I showed my note happily to the camera with an expression of delighted surprise on my face, for entertainment value.

I presume this is some TV experiment about whether people pay attention or not. I have no idea what for, though. I love Medialand sometimes. :o)

Please let me know...

Further to my post earlier today about my getting a free fiver from the man in the sandwich board, I am curious as to what it was about. So I have a request: if any of you happen to see the programme that it was for, can you let me know? At the time I felt it important to move on quickly to avoid the possibility of fucking up his experiment, which I surmised was about setting out to prove that few people would ask for the fiver. I figured that if I hung around too long, it might give more passers-by the wherewithal to join in when they might not have done otherwise.

Cheers. :o)

ETA: Apparently I was on the BBC Ten o'Clock news! Anyone see it? Tell me more!

BBC News

Hurrah! I really didn't have it down as being for a news programme. But I've now seen it. :o) Request to my geek (or simply more techno-competent than I am) pals: is there any way of saving the file of today's broadcast? Obviously they'll update with the new show each day, and I'm not sure how to go about filing away my moment of fame.

I'd like to keep it though, as it is rather fun. :o)
