Will Forte and Jason Sudeikis masterfully serenade each other on 'Fallon'

Sometimes you can fight the feeling, and sometimes you can't.

Will Forte and Jason Sudeikis would have to be put in the column of people who cannot fight this feeling, as the actors (who play brothers on Last Man on Earth) sang a little ditty to one another on The Tonight Show. Yes we're talking about REO Speedwagon’s I Can't Fight This Feeling which we assume is stuck in your head now. The SNL alums put their very personal spin on it, and even Jimmy Fallon had to get involved.

Sometimes you just want to see two comedians having a good time. Sometimes that's what you need.
