A test for being drunk

|A police officer pulls over this guy who had been weaving in and out of the lanes.He goes up to the guy's window and says, "Sir, I need you to blow into this breathalyzer tube."The man says, "Sorry officer I can't do that. I am an asthmatic. If I do that I'll have a really bad asthma attack.""Okay, fine. I need you to come down to the station to give a blood sample." "I can't do that either. I am a hemophiliac. If I do that, I'll bleed to death.""Well, then we need a urine sample.""I'm sorry officer I can't do that either. I am also a diabetic. If I do that I'll get really low blood sugar.""Alright then I need you to come out here and walk this white line.""I can't do that, officer.""Why not?""Because I'm too drunk to do that!"
