The guys from Monty Python enlisted Mick Jagger to make a promo video for their upcoming live shows. In the clip, Mick rips on the guys...but the joke is, he's ripping on HIMSELF, too.

He calls the Python guys, quote, "a bunch of wrinkly old men trying to relive their youth and make a load of money."

And he adds, quote, "Who wants to see that again? It was really funny in the '60s. The best one died years ago. Maybe back in the '70s it was fantastic...it was the funniest thing.  We've seen it all before.  I mean, they've put it all up on YouTube."
