The Irish beat the Spartans 38-18 for their third win in four weeks.
After snatching the win at Spartan Stadium, the Irish gathered in the visiting locker room. Kelly bumped around with his players to the song Congratulations by Post Malone, even turning his hat backwards.
The Megaphone Trophy was then brought into the room and the crowd exploded. Kelly picked up the Megaphone and jumped into the air as the players screamed. One player even picked the coach off the ground.
"That's a Megaphone," he yelled as he held the trophy over his head.
"My wife informed me that I cannot decline any dances with her in the future," Kelly told the Chicago Tribune on Sunday after video of the celebration surfaced.
"I love my guys. I love being around them," Kelly told the school's athletics website. "They're fun. They do the right things."
"We don't have a lot of guys on lists--they pay attention to all those things. So when you have those opportunities to enjoy it--they're kids, they're young, and sometimes we need to share that with them and be young. Even though I might not look it or act it at times, you're with young guys all the time, and it's important that you get to share that with them. I made a promise to them that we'd get that megaphone back, so I wanted to make sure that we were able to present it to them."
Notre Dame now leads the all-time series 49-29-1 against the Spartans. Mark Dantonio is 4-5 against Notre Dame while coaching against Notre Dame while Kelly is 4-2 against the Spartans at Notre Dame.
The Irish host Miami University at 5 p.m. on Saturday at Notre Dame Stadium in South Bend, Ind.
