During Tina Fey's visit to "The Tonight Show Starring Jimmy Fallon" to promote her new film with Amy Poehler "Sisters," Jimmy Fallon decided to put Tina's impression skills to the test.

After a questionable Robert De Niro impression, Tina throws out a couple of surprisingly good impressions.

Check her incredible talent on the video below.
