Charlie Day will throw down against Ice Cube in their upcoming comedy Fist Fight, which hits theaters this weekend, but first the It's Always Sunny in Philadelphia actor has to get past #UFC star #NateDiaz.
In a hilarious new promo video for the film, Day gets locked in a miniature Octagon with the Stockton bad boy, while Ice Cube enjoys the brutal beat down from the sidelines.
"C'mon Charlie, don't be scared," Diaz says in the clip as he pummels him with punches and drags him across the canvas.
This isn't Day's first tussle with a mixed martial artist, as he and Ice Cube had a faux sumo wrestling match against UFC light heavyweight champion Daniel Cormier and retired UFC star Kenny Florian on a recent episode of UFC Tonight.
Unlike Diaz, K-Flo and DC were a bit easier on Day during their scrap.
In addition to the Fist Fight promo tour, Day got the chance to hang out with fighters while filming a recent episode of It's Always Sunny in Philadelphia. Charlie and Mac bring their disgusting, alcoholic workout drink "Fight Milk" to the UFC, which doesn't exactly sit well with Donald "Cowboy" Cerrone's stomach.
Fist Fight punches its way into theaters on February 17.
