Jimmy Fallon and Kate McKinnon may be known for their stellar impersonation skills, but not so much Josh Brolin. All three faced off in "First Impressions," a game where the player must imitate a celebrity they have never impersonated before.

Brolin was up first and had to impersonate Regis Philban, and it took the actor a while to really get into it. Fallon thought Brolin was doing his best Alec Baldwin at first, but McKinnon and the "Tonight Show" host finally figured out that it was Philban. For his second turn, the "Hail, Ceasar!" actor drew Kim Kardashian and didn't really do an impression of the reality star, but he just asked McKinnon and Fallon to imagine him with a large behind.

McKinnon, who is known for her great impressions of people like Justin Bieber and Hillary Clinton on "Saturday Night Live," broke out the always recognizable impression of Christopher Walkin, followed later by Pee-Wee Herman. Fallon was up last and pulled Mike Tyson for his impression and easily lisped his way through the boxer's distinctive voice.
