When Tyler Joseph and Josh Dun — aka the alt-rock duo Twenty One Pilots — watched the GRAMMYs from Joseph's living room in Columbus, Ohio, early in their career, they made a pact: if they ever won a GRAMMY, they would accept the award in their underwear.

In 2017, they fulfilled that promise. Stripping off their pants on their way up to the stage, they accepted the GRAMMY for Best Pop Duo/Group Performance for their hit "Stressed Out" in suit coats and boxers. "Not only is this amazing, but I want everyone at home to know to watch out. You could be next," Joseph quipped. "Because anyone, from anywhere, can do anything — and this is that."
