On last night’s Jimmy Kimmel Live!, the Jonas Brothers faced off against superfan Jessi in a game of “Who Knows Jonas?” — and lost. I blame Nick, who really should’ve known what he wanted to be if he wasn’t a musician. (My favorite part is when Jessi yells “Cheating!” as the brothers stall. She’s in it to win it, boys.)

How many questions would you have gotten right? I’d have scored a big fat zero, however, I’m seriously contemplating going to see their 3D Concert Experience, in theaters Feb. 27, as a crash course (and because I want to watch young girls try to reach out and touch them).
