Mark Cuban and Donald Trump are no strangers when it comes to Twitter beefs. The two billionaires have had their fair share of back-and-forth jabs about anything and everything–from who’s television show is better to who is going to take over the world and even who is better looking.

After the Mavericks victory over the Atlanta Hawks Monday night, Cuban and Trump were back at it again. After a few tweets to each other, Cuban proposed a way to settle their disagreements the only way two billionaires should–with a Harlem Shake duel.

Trump has yet to respond to the proposal so who knows if they will actually do it. All we know is we would love to see this go down.
