If you go to Penn State and you decided to bail when your friends asked if you wanted to go to Champs last night (April 5), you're probably regretting your decision this morning.

The Jonas Brothers decided to surprise fans at the local college bar and play a little five-song set, where they performed their new single "Cool" for the first time live.

According to Rolling Stone, JoBros — who are self-proclaimed Nittany Lion fans — were introduced by Penn State’s head football coach James Franklin. Aside from giving their new song its live debut, the newly reunited trio also played their recent comeback single “Sucker,” as well as their 2007 hit “S.O.S.,” their 2008 hit “Burnin’ Up” and covers of The White Stripes’ “Seven Nation Army” and Busted’s “Year 3000.”

From the looks of Joe Jonas' social media, his fiance Sophie Turner was also at the gig, taking shots with the crowd. Because, you know, that's a totally normal Friday night on the Penn State campus.

The Jonas Brothers live streamed the performance on Instagram, and one smart fan uploaded it to YouTube. Watch them play "Cool" and check out Joe's amazing Twitter post below.
