Creep-o-Meter

A Creep-o-Meter is a meter owned by Scott Wozniak which presumably tracks how creepy it is around you, the item appears in the episode Night Trap.

In Night Trap
When Scott Wozniak says he's been on a strict anti-calender agenda the entire year he wonders why his Creep-o-Meter and Jeep-o-Meter go as high as they can, he then looks around and after a small observation, he assumes it's Halloween.
