Who knew Jack Black was a K-pop fan?

The actor-comedian appeared on South Korean network MBC's Infinite Challenge variety show this week, where he—along with his wide variety of facial expressions—attempted to imitate a number of K-pop songs in the hopes that the show hosts would understand which tracks he was referencing.

"Oh my God, it's happening! This is really happening," Black exclaimed as headphones were placed on his head.

Then, while listening to the songs and without the ability to understand most (if any) of the lyrics, the entertainer hummed, sang—in some ridiculously garbled made-up language—and motioned his way through the tracks. And, miraculously, it seems the show hosts were able to guess his selections... even the ballads!
