Billy Eichner's show Billy on the Street just took a very impactful turn.

Yes, more impactful than caroling with Amy Poehler or ambushing innocent tourists with Julianne Moore. 

This time, Billy on the Street hit the street with none other than the Christmas king himself, the one everyone draws to mind when they think of Christmas cheer. Yes, we're talking about Will Ferrell. 

What do the completely alarmed pedestrians on the street win if they answer Wil and Billy's urgent Christmas movie trivia questions? 

One single dollar. Worth it? Totally. 

There's a lot of screaming in petrified people's faces, a lot of running around in those snazzy holiday pajamas, and a totally subjective and hilarious line of questioning. 

We have a feeling this particular episode will change the way we view Christmas movies forever.

Watch the video below to see the mayhem ensue for yourself.
