Nintendo Switch's new fighting game Arms made its way to Conan O'Brien's Clueless Gamer segment, and actor Will Arnett joined the show to take on Conan in the head-to-head (and fist-to-fist) combat.

While we did get to see some of the unique fighting gameplay, most of the segment was devoted to a verbal sparring match between the two actors and their "disdain" for each other. The loser of the Arms match had to make a video explaining why they love the winner. The kicker was that "sick burns" were counted in the final tally, and needless to say, there were plenty.

We won't spoil the outcome or the ending friend video, but Nintendo should take a clue and add a social feature where "sick burns" from an in-game chat are added to the score. Could make things even more interesting.
