A policeman pulls over a driver for swerving in and out of lanes on the highway. He tells the guy to blow a breath into a breathalyzer.
''I can't do that, officer.''
''Why not?''
''Because I'm an asthmatic. I could get an asthma attack if I blow into that tube.''
''Okay, we'll just get a urine sample down at the station.''
''Can't do that either, officer.''
''Why not?''
''Because I'm a diabetic. I could get low blood sugar if I pee in a cup.''
''Alright, we could get a blood sample.''
''Can't do that either, officer.''
''Why not?''
''Because I'm a hemophiliac. If I give blood I could die.''
''Fine then, just walk this white line.''
''Can't do that either, officer.''
''Why not?''
''Because I'm drunk.''
