Dan Carpenter Misses Extra Point, Throws Helmet, Hits Himself in the Face [VIDEO]

"You had ONE job."

That's the phrase almost all Buffalo Bills fans utter when Dan Carpenter misses the extra point....something that happened all too often this season (85.2%).

Yesterday after Carpenter missed again, he got so mad he threw his helmet on the ground when he got to the sideline.

But to add insult to injury, the helmet bounced off the ground and smacked him square in the nose.
