Fallon even created a new (entirely fake) Olympic sport for the girls to play with him called "Hungry, Hungry Humans", an obvious play on the children's game "Hungry, Hungry Hippos".
USA 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.
Joining forces with Fallon, actor Donald Glover and The Roots' Tariq Trotter, they split up into groups of two to see who could gather the most balls, just like the classic kids' game, but, you know, with people. With so many guests on the show, the late-night show made a decision to have them all play a pretty intense game of Hungry Hungry Humans.
In the end, only one team could take gold, and Hernandez and Raisman came out on top, narrowly beating Douglas and Kocian.
"We totally let you guys win", Jimmy joked.
There is a very thin line between fun, goofy late-night talk-show segment and eccentric rich man forcing people to entertain him by participating in ridiculous stunts.
The 2016 U.S. Olympic women's gymnastics team already made their childhood dreams come true with gold medals during the Rio games.
