Well, you can only be the world's best at so many things. Rory McIlroy is the best golfer on the planet but, if this video is any evidence, he's not the world's best arm wrestler.

That's because a 17-year-old kid from Oklahoma named Brad Dalke arm wrestled No. 1 on Friday at a Nike-sponsored junior golf event at Sage Valley that McIlroy attended.

Dalke torched him.

You can hear Dalke say before he starts "I shouldn't be a golfer" as McIlroy sizes up his biceps. No, I think you can be ripped and be a golfer at the same time.

The dude you beat is proving it.
