'America's Got Talent' Sets Weird New Guinness World Record in Final Night of Audition Rounds

This season of America's Got Talent saw week after week of epic auditions from a slew of hopefuls looking for their big break and a real chance at stardom. On Tuesday, this season's audition rounds wrapped up with some of the best performances yet.

This week's slate of performers included aerialists, acrobats, comedians, a magician, wildly impressive singers and many more!

Host Terry Crews led the mind-blowing slate of auditions, which were overseen by longtime judges Howie Mandel , Heidi Klum , Sofia Vergara and Simon Cowell , who were on the lookout for some truly exceptional performers.

What they got were a handful of jaw-dropping acts and a few truly unexpected, somewhat weird moments -- and a record-setting accomplishment.

One of the biggest highlights of the night came from 19-year-old Los Angeles nativeBrooke Bailey who blew the judges' minds with a cover of Aretha Franklin's "Ain't No Way."

However, despite all the judges getting two Golden Buzzers this season, none of them had any Golden Buzzers left to give out, so she had to settle for four enthusiastic yes votes, and a lot of love.

The night came to a close, however, asNick Manning took the stage, and explained to the judges how he planned to audition by setting a Guinness World Record -- specifically, the record for the most underpants pulled on in 30 seconds.

This isn't the first time a contestant auditioned by trying to set a world record (and I've never understood how that counts as an audition. Like, how is that an act that could be replicated on a Las Vegas stage if they did somehow win the season?). Like most world record attempts seen on AGT , Manning didn't succeed.

However, he wasn't quite done! Employing the help of the audiences and the judges, Manning came prepared with thousands of pairs of brand new underwear, and passed them out to everyone in the building.

With the adjudicator on hand, Manning and the audience tried to break anotherGuinness World Record -- the record for the most people gathered in one place wearing underwear on their heads.

Even Cowell got in on the awkward fun, and the audience had a bit of a dance party for a set amount of time before the adjudicator tells them that they've successfully set the record! AGT is now in the Guinness Book of World Records!

However, despite the quirky fun, all of the judges are in agreement that Manning didn't accomplish his own record, and the one they did set wasn't exactly challenging. So, despite setting the record setting, it was still four no votes from the judges.

Here's a look at a few of the night's other biggest, most epic performances:

ET spoke with the judges on the AGT red carpet ahead of the season 19 audition rounds, and they opened up about why giving each of them a second Golden Buzzer is a real game changer.

"Talent is subjective. When you put a singer next to a dancer, next to a danger act,next to a magician -- they each need their own buzzer!" Crews shared. "I just think it's perfect! And I've said this before, AGT is consistently evolving... [and] it's getting better every time a new evolution comes out."

Cowell -- who created AGT and also serves as an executive producer on the series -- came up with the idea for the second Golden Buzzer, and explained to ET that the idea came to him when he considered "the amount of time and effort these people put into this act and where this can go."

"People fly in from all over the world, as well as the American artists, and you are seeing the [amazing] things," Cowell gushed about the magic of the show. "The 70 times I've just gone, 'How did you come up with that idea?!' That's what I love about the show, you know? It continues to surprise you."

America's Got Talent airs Tuesdays at 8 p.m. ET/PT on NBC.
