Yankee Doodle went to town riding on a pony. Stuck a feather in his hat and called it macaroni. By punctuation and sentence structure, the feather was called macaroni, but I think you could make a case for the hat being called macaroni, too. Not the pony. Yankee Doodle wasn't bright so he didn't know a feather from macaroni. Personally, I like he didn't know his ass from his elbow. =^,.^=
