shayman, My Visit to the Dentist.
Part 1: The dentist is doing really well! He says "Your teeth are pretty clean, good job."Part 2: Dentist notes "Hmm this filling is pretty old, it should be replaced."
Part 3: I ask "How old do you suppose it is?"
Part 4, where all the good will built up in Part 1 evaporates: "Oh, probably from before I was born"
