Just watch an episode of the greatest show ever created, The X-Files, and when you see one of the following occurrences, drink that much of your beverage.
Every time Scully is scene examining internal organs of some corpse.
If Mulder or Scully is in a dark scary place and one of them drops or loses their flashlight. If Mulder mentions that something could be paranormal and another character thinks he's joking. If Mulder just happens to know some obscure case reference or fact that just happens to be similar to the case that they are working on. Anytime anyone goes into a dark and scary place and it is obvious that they should NOT be there. Every time Scully misses proof of a paranormal event.
