First appearance: Invasion of the Body Snatchers (1956)
Ever have a night where you just can't fall asleep? You should pretend you're in Invasion of the Body Snatchers. That way you can say you're not sleeping in order to prevent an emotionless, vegetable clone of yourself from taking over your life. The next day you can pretend that you ARE the vegetable clone and that's why you're just numbly going about your daily routine. Its fun! Seriously though, this was a pretty creepy movie. The remakes aren't bad either (except for that Nichole Kidman one).
