WATCH: Conan O'Brien spots a hilarious 'nervous tic' that shows when Jeff Sessions is lying

Conan O'Brien decided to have some fun with Attorney General Jeff Sessions' Senate testimony on Tuesday, as he had his graphics team concoct a hilarious "nervous tic" that supposedly shows when Sessions might be lying.

During a segment on his Tuesday night show, O'Brien said that he had spotted a "nervous tic, almost like a poker tell, that comes out at times when he may be lying."

He then cut to footage of Sessions saying he never remembered meeting Russian ambassador Sergey Kislyak at the Mayflower Hotel in Washington D.C. last year -- and as soon as Sessions finished talking, his ears started to comically wiggle as he looked ahead nervously.

The segment then cut to a clip of Sessions saying that, "people are suggesting, through innuendo, that I have been not honest about matters, and I've tried to be honest."

At this point, Sessions' ears began flapping rapidly like a bird's wings.
