LOUISVILLE, Ky. (WDRB) -- It's hard running around in a mascot costume, but having your pants fall down makes it even worse.


One poor kid in a mustard costume kept tripping over his pants during the Kansas City Royals' Hot Dog Derby.


The annual foot race at Kauffman Stadium was right before yesterday's Giants-Royals game. It featured relish, ketchup and a mustard-topped hot dog -- but mustard even face-planted during the Derby.


The race on weekends is always a crowd favorite.
