Jamie: Okay Vicki, you're goin' to be my lie detector at lunch so we can find out who stole the test. Okay?
Vicki: Okay. When I touch a person, my hand will detect any changes in their skin temperature and pulse rate which will indicate if they are lying.
Jamie: Right. Just grab their hand, ask a couple of dumb questions like "What's their favorite color?". Then we hit 'em with the big one about the test. Understand?
Jamie: We don't want them to know what we're doing. We've gotta set up some signals. Now if they're telling the truth, I want you to laugh, ha, ha, ha! And if they're lying, sneeze, ah-choo!
Vicki: Truth: Laugh, ha, ha, ha! Lie: Sneeze, ah-choo!
Jamie: Right. Just don't let go of their hands. Come on.
