This is how they roll - literally! 

Making the rounds to promote her new TV series "Extant," Halle Berry teamed up with Jimmy Fallon on "The Tonight Show" Tuesday to show viewers just "how they roll."

For the demonstration, the pair grabbed each other's ankles to form a human hamster wheel and actually rolled around the set.

"I'm not going to peek, I'm not going to look [up your dress]," the late night host promised the 47-year-old actress as she moved into position, before they wowed the audience with five impressive forward rolls.

As if that wasn't crazy enough, Fallon even created one of the punniest hashtags ever to commemorate the event -- #ThisIsHalleRoll.

Gotta love Jimmy!
