why: because I never knew who these guys were until last night when they had a performance of the video posted below ("A Slight Figure of Speech") on Jimmy Fallon, but I like 'em and you should too.
P.S. - Don't be worried, I didn't post the wrong video on accident - they released their video through Funny or Die which I think is hilarious. If you wanna skip the comedy in the beginning and get to the song, fast forward to about 3:00
