Seth MacFarlane does killer Liam Neeson impression on "The Tonight Show Starring Jimmy Fallon"

Jimmy Fallon gave "Family Guy" creator Seth MacFarlane a challenging test of talent Tuesday night, with the Celebrity Impression Generator. Guests have to improvise a bit with a celebrity and random topic spun on wheels.

MacFarland spun Liam Neeson and Time Warner Cable as the topic, and he killed it, or at least he threatened to.

"I have a particular set of channels, if you would like to purchase these particular channels, I will come to your house and install your cable. And that will be the end of it. And if you don't, I will look for you, I will find you, and I will kill you," in the styling of Neeson's menacing Irish accent from "Taken."

Fallon wasn't there just to watch -- he took a spin, too and got Jerry Seinfeld on the topic of Uber.
