Whoever said less is more was lying. More is more, and more is always better, and more Jonas Brothers are always better than less Jonas Brothers. Or fewer. Whatever. Four's better than three, especially when the fourth is Bonus Jonus Frankie, who stole the show right out from under his three brothers, who pretty much willfully handed it over to him and let him pick from the swarms of JB fans desperate to leave the sticky streets and meet their heroes inside the air-con'ed studios of TRL.
Check out exclusive behind-the-scenes footage of the all four Jonas Brothers on their fourth and final TRL episode of the week, and check out BTS video from Wednesday and Tuesday.
Plus, get an up-close-and-personal look at the JBs' fans, and check out this most-extreme recappage package of all of the X-treme Jonas events of the past weekend.
PS: Happy 19th birthday, Joe Jonas! We love you, with or without the Erik-Estrada-in-CHiPS 'stache!
