Last night on "Late Night With Jimmy Fallon," the Jonas Brothers broke free from their softball career to return to the business of playing music for adoring fans. Not only did Kevin, Nick and Joe rip through a solid rendition of "Paranoid," they also made a guest appearance on the show's segment "Lick it for 10" (where audience members lick things in exchange for 10 bucks). The segment featured a bunch of "Harry Potter"-themed items as well as a fun cameo. That clip is below, and the performance of "Paranoid" is hiding after the jump.
