Impressionist Chloe Fineman may have just done actors Meryl Streep , Keira Knightley and Jennifer Coolidge better than they do themselves. (OK, thats not possible, but you get our point.)

The Saturday Night Live star showed off her impersonation skills on The Tonight Show Thursday, assuming different personas when she got her cue. But she had to be in character while improvising small talk with host Jimmy Fallon .

How else could you get Finemans Knightley to hilariously mouth the word gourd, and her Streep to say autumn bottom?

Fineman, along with SNL impression virtuoso Melissa Villaseor , just got some copycat company in newly hired player James Austin Johnson , who does a heckuva Donald Trump .

But as Fineman has proven on The Tonight Show before , shes one of the best impressionists in the business.
