My Hero Zero? Nope. Penn State football during the Pep Rally? Still no.

The roaring you might have heard Saturday afternoon from the Bryce Jordan Center erupted from Penn State THON's crowd when Mason Ramsey, famously known on the internet as the "Walmart Yodeling Kid" viral sensation and internet meme, took the stage.

Donning his signature white cowboy hat, white-button shirt, blue jeans and studded boots, 12-year-old Ramsey opened his surprise performance with original song "The Way I See It" off his new EP, "Famous."

The Daily Collegian originally reported that Ramsey was set to make an appearance at THON after confirming it with a member of his team.

Spectators in the stands of the BJC flashed their phone lights in the rhythm of the music, as Ramsey sang some of his songs from "Famous," including "I Saw the Light," "Jambalaya (On the Bayou)" and "Yo Da Lady Who." Ramsey also covered a few classic country hits, such as "Ring of Fire" by Johnny Cash and "Hey Good Lookin'" by Hank Williams -- one he dedicated to "all the ladies" in the crowd.

"So, everybody's been waitin' for this," Ramsey said before singing his most recent single "Famous."

But perhaps the biggest reaction from the crowd of dancers and spectators alike was when they heard Ramsey sing "Lovesick Blues," the same tune he went viral for singing in an Illinois Walmart back in 2018 — a sea of phones capturing the moment.

"Thank you guys so much," Ramsey said in response to the loud cheers. "Today is a very important day to you guys, and to me." He then asked the crowd to sing "Happy Birthday" to his drummer, Jeremy, which was met with loud applause.

But Ramsey wasn't done there. "Let's get this party started even more," he said before strumming his guitar. Ramsey later entertained the attentive crowd by tossing his guitar pick into the crowd, tipping his hat and busting a move. Ramsey even recorded a video with the crowd once he finished his set.

"I love you guys too," Ramsey said to the crowd. ""If the good Lord's willing and the crick don't rise, see y'all again next time!”
