Today's anniversary of the (European) discovery of the Caribbean reminded me of a sketch on one of the comedy/variety shows when I was a kid -- it was either _Rowan and Martin's Laugh-In_ or _The Smothers Brothers Comedy Hour_:
Boy Columbus is in school and the teacher is telling the class that the world is flat. Then Columbus stands up dramatically and declares, "No! You're wrong!"
The teacher is taken aback and demands, "What do you mean?"
Columbus goes on, "The Earth IS'NT flat. The Earth is shaped... like a CHICKEN!"
