Well this is an interesting game!
While on The Tonight Show, James McAvoy and Jimmy Fallon compete in the "Ramen Challenge." They each have to slurp up really long noddles from the soup bowl. Whoever finishes their noodles and shots first, wins.
The loser has to wear a costume and do a dance!
There is no way to explain this game without sounding dirty... even Fallon has trouble explaining it without laughing!
