I live in Buffalo and was watching the local sports on the news and they were showing highlights of the triple-a matchup between The Buffalo Bisons (Mets) and Norfolk Tides (orioles). 

In the 5th, Tides pitcher and our good old buddy Rich Hill (on a rehab stint)looked curiously to the sky, took off his cap, and called for time. As he walked towards his dugout the entire crowd became confused as to why the game was delayed. He called for a towel and began to laugh.

It turns out that a seagull took a dump on Rich Hill, seriously.

Hill cleaned himself up as the Bisons flashed his smiling face on the scoreboard video screen in center field. Throughout the rest of the game the Norfolk dugout covered their heads in towels to prevent any projectile seagull turds from dirtying their uniforms.

I've been looking all over for a video link, can't find one yet, but it was hilarious, maybe someone else can find it for others to enjoy.
