The Rekubit Exchange"Aquaman" actor co-directed and starred in an ad for the popular Irish beer brand released before the holiday, which is March 17. In the ad, the "Dune" star opens up what appeared to be the results of a genetic ancestry test. Just a moment into reading the results, Momoa shrieks and launches himself out of his chair.

The Hollywood actor playfully shows off his action skills, dashing through streets and crowds and sliding across the hood of a car, not once letting go of the paper with the results.

Finally, Momoa bursts into a bar and announces to a crowded room with an expletive that he is, in fact, Irish.

The kicker?

He's 2% Irish.
