1. Imagine that you are standing in a train yard when a train comes barreling along, out of control
  2. You look down the tracks and see that there are five people tied up, trapped, directly in the path of the train
  3. You're standing near a lever that you can use to redirect the train to a different track running parallel to the first
  4. But then you notice that one of your cousins is tied to the parallel track, and that by diverting the train you'll be killing him or her
  5. And then you realize that the group of 5 people is actually the cast of The Big Bang Theory
  6. You only have a few seconds to act
  7. What do you do?
  8. And how much would it influence your decision to know that the last person to touch the lever that redirects the train had semen on his hand?
