You know that weird phenomenon that happens where people with accents somehow lose them when they sing? Yeah, not this guy! Meet Irishman Mick Konstantin.

Mick is a ukelele player who has gone viral recently because of his very catchy song, "There’s Only One Conor McGregor."

It takes a little while to get to the hook, but we promise you, once you hear it, you'll be humming it all day. The song even caught McGregor's attention and now Konstantin will be joining him later this month in Vegas to watch Conor's fight against Floyd Mayweather, Jr.!
