This is a discussion from dinner tonight at the Catt house (Peggy's family):
Emma (Peggy's 15 yr. old sister): "In Jingle Bells, what does it mean when it says bells on bobtails ring?"
Sarah (Peggy's 25 yr. old sister): "BOB's TAIL! The horses name is Bob and the bells are on his tail."
The funniest part about this is that Sarah was dead serious and the pause of silence afterward made it a golden moment. After a short discussion, Jordan (the Catt mom) came to the rescue and explained that a bobtail is a "bobbed" tail which is a tail that has been cut short.
