In the words of Paul Blart, nobody wins with a headbutt.

That fact has never been more evident than it was during a recent MMA fight, which ended abruptly after the two fighters banged their heads together.

The double headbutt was unintentional, but it’ll likely be enough for both fighters to write off the possibility of ever using the illegal move on purpose. The two combatants were visibly shaken up following the big blow, and they each required medical attention while laying in the ring.

The strangest part of the video, however, might be the playing of “We Are The Champions” in the background. For some reason, the song just doesn’t fit the scene.
