U.S. gymnastics team members Gabby Douglas, Laurie Hernandez, Aly Raisman, Simone Biles and Madison Kocian joined Fallon, The Roots' Tariq "Black Thought" Trotter, and guest Donald Glover for a game of Hungry Hungry Humans.
The contestants split off into four teams -- Trotter and Glover, Fallon and Biles, Douglas and Kocian, and Raisman and Hernandez -- and went head to head in a wild, kinetic game, where they tried to grab dodgeballs with plastic buckets while being pulled and pushed by their teammates, who had a hold of their ankles.
Despite winning four gold medals at the Rio Games, Simone was stuck with another bronze finish in Hungry Hungry Humans. No matter how enthusiastic Fallon was, their score of 24 balls just didn't stack up.
The top two places were separated by only one ball, with the winners scoring 30 and the runners-up nabbing 29, and it all came down to the Blue Team (Raisman and Hernandez) and the Green Team (Douglas and Kocian).
After some expert tension building by announcer Steve Higgins, Raisman and Hernandez walked away with the win, which Fallon refused to accept with grace.
"We totally let you guys win," he joked, after hugging the victors. "We talked about it before the show, so congratulations. You guys are really cool."
