Q: What is responsible for sudden movements in the body?

A: It could be that you are tired, or tense, or having a muscle spasm.

It's more likely you have been impregnated by an alien parasite and are about to give birth to a horrifying creature with razor sharp claws and teeth and acid for blood.

There's only one way to be sure: We are going to have to kill you and burn your body.

No, an X-Ray would take minutes and we simply do not have the time.

If my theory is right, you'll thank me. It would be pretty painful to have that monster burst out of your chest.

If my theory is wrong, don't worry, I will console your very attractive wife. I'll tell her you went mad and tried to kill us all, so she won't feel bad.
