Hitch-hikers are scary even when they aren't on TV. Have you ever seen any of the dudes flagging down cars in the northeast? If we've learned anything from urban legends, it's that the person posting in your backseat is more often than not a ghost, a killer, or some combination of the two (though rarely Ghostface Killah).

Incorporate Twilight Zone into the mix and you've suddenly got a perfect recipe for sleep deprivation. We certainly suffered from it the first time we caught this award-winningly frightening episode in which driver Nan Adams (Inger Stevens) keeps crossing paths with a hitch-hiker (Leonard Strong) she suspects is trying to kill her. You just try not to pee your pants during that final glimpse in the mirror when the guy unleashes his, "I believe you're going...my way."
