Watch Josh Brolin's Kim Kardashian Impression on 'Tonight Show'

'SNL' star Kate McKinnon impersonates Christopher Walken, while Jimmy Fallon attempts Mike Tyson in 'Tonight Show' game

Josh Brolin impersonates Kim Kardashian – with help from a tissue box – in a goofy 'Tonight Show' game

Jimmy Fallon recruited Josh Brolin and SNL cast member Kate McKinnon for a round of "First Impressions" during Tuesday's Tonight Show – and the obvious highlight was Brolin attempting to impersonate Kim Kardashian. Unable to recreate the reality star's accent, the Hail Caesar! actor held a tissue box against his ass and flipped back his imaginary long hair. To his credit, Fallon and McKinnon guessed correctly. 

Brolin started the game with a spot-on characterization of Regis Philbin's impatient shout – "I was riding my snowblower around all weekend. My ass is killing me!" – though he relied on easy hints to get a correct guess. McKinnon struggled with Christopher Walken but still nailed the actor's overall tone ("I like going to the petting zoo to feed the baby goats"), and Fallon nailed Mike Tyson's soft-spoken lisp ("You guys, I'm so excited: There's less than a week until the Iowa caucus!")

In December, Tina Fey joined Fallon for "First Impressions," with the duo mimicking Morgan Freeman, Jack Nicholson, Elmo and more.
