Jimmy Fallon knows a thing or two about having fun.
He's always playing the most entertaining games with his celebrity guests on The Tonight Show.
Now, we guess he's out of ideas because he's turned to drinking!
But at least he has Margot Robbie to drink with. And at least they're playing flip cup while drinking.
Not sure what flip cup is exactly or just wanna see Margot Robbie give Jimmy a run for his money at a college drinking game?
Check out the video (above) and find out who's the better cup flipper! Or should we say "flip cuppper?" LOLz!
