Free Running Sketch

Some time over the last couple of years I saw a sketch about people doing someparkour/free running. They were all usless at it, but behaved as though they were doing it correctly. I think it was performed by someone well known, but I've no idea who. Can anyone tell me?

There are numerous examples. I liked this:

Maybe the one you're talking about?

Or French & Saunders

Could be this one?

Thanks for that. Very helpful.
