A man walks his horse into a liquor store...no, it's not the start of a joke. It really happened at Patriot Wine and Spirits in Warren, Rhode Island. Eyebrows were raised, especially when the horse wasn't able to control himself inside the store...making a mess of the carpet on the way out. The horse's owner, Bill Saviano of Rehobeth, says he did it on a dare, and shrugged off the entire incident. Management has posted this new sign. Watch video of the horse in the store below.
