The horse head is really enjoying a moment in the world of sports right now. No, really, it is. Just last week, the Yankees revealed that they've been having a lot of success lately, ever since their reliever Shawn Kelley started wearing a creepy horse head before games. President Obama was recently spotted shaking hands with a man in Denver (a Broncos fan, we presume) who was wearing a horse head at the time. And last night, a tennis fan (seen in the photo above) was asked to remove his horse head at the 2014 U.S. Open during a match between Gael Monfils and Richard Gasquet. So you see what we mean, right? The horse head is really flourishing right now.

It's not the first time it's flourished in the world of sports, though. In fact, for whatever reason, the horse head has become somewhat of a staple in sports over the course of the last few years. From NFL games to soccer matches to horse-racing events, we've spotted sports fans wearing horse heads everywhere. Just take a look at these 25 Ridiculous Photos of Sports Fans Wearing Horse Heads. So strange.
