Own goals are, by definition, bad, but this own goal in a Bundesliga matchup between Mainz and Augsburg is really, really bad. Augsburg goalkeeper Marwin Hitz made a glancing save on the initial shot from Mainz, but the ball hit off the post and trickled back in front of the net. So, trying to clear the ball out of harm's way, his teammate kicked it square into his face and into the goal. I haven't stopped watching yet.
Here's a Vine of the whole thing:
Mainz won 3-0.
