The rules of Name Drop are, as always, simple. There are six clues. They begin easy and get harder, or begin hard and get easier, depending on your definition of easy. You may guess after any clue. You get more points for guessing sooner. The alligator is not a valid guess and never has been, no matter how many of you write in.
