It turns out that Twenty One Pilots’ pantless Grammy acceptance speech has a sweet story behind it.

Tyler Joseph explained that before finding fame in the music world, he and bandmate Josh Dun were watching the Grammys from home together with friends — in their underwear.

“As we were watching we noticed that every single one of us was in our underwear,” Joseph said. “Josh turned to me, and he said, ‘If we ever win a Grammy we should receive it just like this.'”

And so they did.

“Anyone from anywhere can do anything, and this is that,” said Joseph before leaving the stage.

The two accepted the award for Best Pop Duo/Group Performance for their hit “Stressed Out.”

After the the show went to commercial, host James Corden appeared in his underwear, joking that he too promised himself that if he ever got to host the Grammys he’d appear pantless.
