There is a need for a standardized scale of creepiness. I propose "Uncle" as the unit. Here are some examples to help you calibrate your creepiness scale to this new standardized one.
  1. 1 Uncle (just a little creepy): a guy sitting in a parked car watching people go by
  2. 2 Uncles: the same guy, but at night
  3. 3 Uncles: same guy getting out of his car and following you
  4. 4 Uncles: ... wearing only a trenchcoat
  5. 5 Uncles: ... on a deserted street.
  6. Lord help you if you exceed 5 Uncles. 8 Uncles is the highest dose ever known to be survived.
