The Jonas Brothers are making music together again [1], but they still aren't afraid to poke a little fun at each other. During their week-long appearance [2] on The Late Late Show on Wednesday night, Kevin, Joe, and Nick discussed the side effects of forming a band with your brothers [3]. While there are some positive effects, like being able to call your Verizon family plan a business expense, there can be a few awkward moments as well. Throughout the segment, Nick just couldn't help but bring up his "very, very successful" solo career with a sly smirk. Honestly, when did sweet Nick turn into a complete savage? Watch his brothers hilarious reaction to the moment ahead.
