Thanks to HockeyFarm for this. From the story:
The owner of Patriot's Liquors in Warren called police after 51-year-old William Saviano walked into his store with a Shetland Pony.
It wasn't the pony that got the owner upset- it was what the pony did when inside the store.
The pony, apparently not potty trained, defecated in the store and Saviano did not clean it.

I wonder why the liquor store owner called the cops instead of calling me. He needs to prioritize.
