Mick Jagger is demonstrating his sense of humor as he helps the Monty Python comedy troupe promote their upcoming reunion shows. 

The Rolling Stones frontman is featured in a short video discussing the ten-date run with an assistant, and questioning why anyone would want to watch a group of men well past their prime perform material that's at least 40 years old.  

Jagger then works with his assistant on the set list for the Stones' next show, which he's packing with the band's biggest hits from the 1960s.  He then agrees when the assistant suggests the "Dead Parrot Sketch" -- a classic Monty Python routine. 

Monty Python's surviving members are launching a run of ten shows at London's O2 Arena on Tuesday.  The first date sold out in less than 45 seconds, prompting more performances to be added.  These are the first Monty Python performances since 1980.
