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.''
