It might be 2019 today, but it was the Year 3000 last night at Champs Downtown.

The Jonas Brothers made a surprise visit to State College on April 5 — debuting their new single "Cool," buying drinks for everyone and rocking out with James Franklin.

WE ARE PENN STATE 😎 Thanks for letting us stop by and play a few songs tonight @ChampsPennState! pic.twitter.com/i8Mn1Fizlj — Jonas Brothers (@jonasbrothers) April 6, 2019

It was every washed-up, former 10-year-old fangirl's dream.

I think seeing @joejonas in a Saquon shirt actually got me pregnant — Marisa Yeager (@marisa_yeager) April 6, 2019

The brothers, who recently got back together as a band, made the trip to State College largely because of Joe Jonas's ardent devotion to Barstool Sports' best college bar Twitter contest. Joe, who spent his 21st birthday at Champs Sports Grill, spammed his Twitter asking followers to vote for Champs.

When Champs won, many anticipated a surprise visit from Joe — and he brought Kevin and Nick along with him, too.

Penn State is such a cult that the Jonas Brothers literally came to @ChampsPennState to perform a concert to help win a social media contest. Gotta live. — Matthew Lownes (@LownesMatthew) April 6, 2019

At around 9 p.m., the Nick, Kevin and Joe Jonas — and their significant others — arrived in Happy Valley via a private jet. At that point, students had been scrambling to get into Champs for several hours, paying a cover of $10.

The brothers drew a large crowd as they made their way into Champs.

saw the @jonasbrothers walk into champs and i think i’m more in awe at how GORGEOUS their ladies are than actually seeing the boys 😫 pic.twitter.com/oqzaIMzq2R — Mariah Selvaggi (@ryeselvaggi) April 6, 2019

From buddying it up with James Franklin to Nick telling the audience he would have attended Penn State had he gone to college (excuse me, what?!), the brothers made the night unforgettable for any Penn State student.

front row for the @jonasbrothers at champs and @nickjonas says “If we had gone to college we probably would’ve gone to Penn State.”YEAH BABY. — Emily Rose (@emilyrose0117) April 6, 2019

While many were thrilled to hear the Joe Bro's new songs, throwback 2000s jams proved to be a major hit, with students loudly yelling out lyrics like, "This is an S.O.S.," "Not much has changed but they lived under water" and, of course, "red dress (red dress)."

However, the night wasn't "cool" for everyone. Students under 21, alumni and commonwealth students found themselves barred from the experience.

every penn state student under 21 tonight if the jonas brothers end up at champs pic.twitter.com/x37rUIV1iB — b 🍓🍓 (@barriet123) April 5, 2019

Only slightly mad that the Jonas Brothers are probably on their way to Penn State tonight to perform at the bar and I turn 21 in 2 weeks. — Madison (@m_ansbach16) April 6, 2019

Me rn running out of my house to drive 4 hours to @ChampsPennState to see @jonasbrothers and Sansa Stark drink dirty sprites like true Penn State trash 💙 pic.twitter.com/1EEMTx7FLq — Alexandra Franklin (@AlexandraAnna17) April 6, 2019

I’m really BURNIN UP about the Jonas Brothers being at Penn State the year after I graduate — Marisa Yeager (@marisa_yeager) April 6, 2019

And while many reminisced on their childhood days of listening to the Joe Bros, other reminisced on the Chili's that previously inhabited the Champs Downtown space.

two jonas brothers and sansa stark are leading a campaign to vote for a penn state bar in some contest, and boy let me tell you, back in my day...that bar was a chili’s pic.twitter.com/7JmXxaLJ86 — evan romano (@EvanRomano) April 5, 2019
