Last night in NYC, Jared Leto, Tomo Milicevic and Shannon Leto played their 300th show at the Hammerstein Ballroom, officially securing a place in the Guinness books for playing the most shows during a single album cycle.

Apparently Jared was the mastermind behind the scheme, telling MTV News it was all his idea. "People started to ask us, with an incredulous look, What the f--- is wrong with you? or they would kind of look at us and be like, 'You guys are still on tour?' And it started to seep in that maybe this was a little bit crazy. And then I remember as a kid, I was a big fan of the Guinness Book of World Records ... so I just started thinking, Maybe we should take a shot at it. "

Mars will play two more shows this week in New York and the proceeds of their very last will be donated to Haiti.
