This question first occured to me after visiting family in Lawton this past weekend.My niece flipped her mother THE BIRD,then all hell broke loose.My Dad says WHERE DID SHE LEARN THAT?My sister ( obviously not thinking clearly)says FROM ME FLIPPING HER DAD OFF.I thought my Dad was going to kill my baby sister(she is 19 years younger than me).Anyhow in the midst of all this I'm thinking I WONDER WHO FIRST USED THIS TIME HONORED HAND GESTURE?I often have odd questions pop into my head at the darndest times.In any case,does anyone know?
