Funnyman Zach Galifianakis is back with his ever-popular 'Between Two Ferns' show on Funny or Die. In the latest episode, comedian Will Ferrell gets in on the strange act.

During the talk show parody, the duo get friendly and begin feeding fruit to each other. One thing leads to another and before you know it, Galifianakis is eating a strawberry right out of Ferrell's mouth.

As if the video wasn't random enough, look for a short cameo from 'Mad Men' star Jon Hamm, who stops by to look for his car keys.

Ferrell is the latest celebrity to appear with 'The Hangover' star on his show. Jennifer Aniston, Sean Penn, and Steve Carrell have all stopped by chat, literally, between two ferns.
