It is amazing the stuff that people will lie about when you catch them red-handed. For instance:
Staff: What happened to your pills?
Joe: What pills?
Staff: The pills your doctor gave you. The ones you were supposed to hand over to us immediately upon arrival.
Joe: I don't know. The doctor never gave them to me.
Staff: That's funny. Because we just called your doctor. He says you left the office with one bottle of forty pills. Where are they?
Joe: ... I forgot.
Staff: right... you're diagnosed with Borderline Personality and drug addiction, but clearly the problem here is memory loss.
Joe: I don't like staff being all up in my business!
Staff: Medicine is our business. Where are your pills?
Joe: ... What pills?
Staff: YOU DIE NOW!
