You know what they say about glass houses, Mick.
Rolling Stones frontman Mick Jagger, 70, joked that the reunited stars of Monty Python are "old, wrinkly men trying to relive their youth and make a load of money" in a promotional appearance for the iconic comedy troupe's new batch of performances. It's all in good fun, of course. See the full (totally meta) clip for yourself.
Jagger is currently on the road with his bandmates (reliving their youth and making loads of money, we're sure) on the Stones' "14 on Fire" tour.
The five surviving members of Monty Python (Graham Chapman died in 1989) will kick off a set of reunion performances this week, with 10 shows scheduled at London's O2 arena over the course of the month. The group has said that these performances should serve as a final goodbye to the fans.
