Lol, sometimes their registered name can be a doozy too. I saw a quarter horse whose name was "USmeltItUDeltIt" and I would pay the $200 or so to have it changed in a heartbeat.
Oatmeal. LOL. Poor thing. So many unimaginative owners out there. At this polo pony barn, all the chestnut horses are "Red", all the bays are "Brownie" and all the blacks are "Blackie."
