A police officer pulls over a man... Officer: Sir, you were swerving quite heavily back there. I would like you to take this breathalyzer test. Man: I'm sorry officer, but I can't do that. Officer: Well why not? Man: I have asthma. If I do that I'll have an asthma attack and die. Officer: Ok. How 'bout we go down to the station and do a blood test? Man: I'm sorry officer, but I can't do that either. Officer: Well why not? Man: I am a hemophiliac. If I do that I'll bleed to death. Officer: Ok. Well how 'bout I draw a line with chalk and you try to walk. Man: I'm sorry officer, but I can't do that either. Officer: Well why not? Man: I'm too drunk.
