3. Will Ferrell, Kevin Hart and Jimmy Fallon
Can you believe that Ferrell and Hart overdo it a little bit? Okay, that’s what they’re both known for, and this is one of those situations that probably should be played as broadly as possible. Ferrell writhes through “Drunk in Love,” Hart serenades his Get Hard cast mate on John Legend’s “All of Me,” and Fallon comes close to stealing the spotlight away from both guests when Drew Barrymore joins him for a spot of Dirty Dancing.
