There are horrible things that should never be done again (i.e. Miley Cyrus twerking). Then there is this: a unique first pitch delivered by retired U.S. Army Sgt. 1st Class Brian Keaton at the Washington-San Francisco game.

Keaton served in the Army for more than 20 years. The veteran was wounded after a bomb exploded in Iraq. Keaton spent three-and-a-half years at Walter Reed National Military Medical Center recovering from a traumatic brain injury and PTSD (post-traumatic stress disorder).

Keaton's first public outing was a trip to Nationals Park as part of an in-game military salute.

The crowd cheered loudly as Keaton took the field to throw the first pitch Saturday, October 4 at the San Francisco vs. Washington game. The Army veteran surprised everyone by crawling, then hurling the opening pitch, grenade-style.

Coming from a military family, this video makes me smile so much! I absolutely love this video.
