Jeep-o-Meter

A Jeep-o-Meter is a meter which presumably tracks if there are any Jeeps close by. 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 Jeep-o-Meter and Creep-o-Meter go as high as they can, he then looks around and after a small observation, he assumes it's Halloween.
