A police officer pulls a man over who was driving erratically. The officer walks up to the man's window and asks him. ""Sir, you are all over the road! I need you to blow into this breathalyzer to determine if you have been drinking."" The driver of the car shakes his head vehemently and says to the officer. ""Oh, I can't do that, officer! I'm an asthmatic! If I blow too forcefully into that tube, I could have an asthma attack and die!"" The officer nods his head, understanding. ""Very well then, sir"" he says. ""I'll just have to take you down to the station to have your blood drawn to see if you have been drinking."" The man again shakes his head, this time even more violently than the last. ""Oh, I can't do that, officer! I'm a hemophiliac! If they take blood, I'll just keep bleeding until I die!"" The officer, visibly annoyed, acquiesces and tells the man. ""Very well then, a urine sample will be fine!"" Once again, the man shakes his head. ""Oh, I can't do that, officer! I'm a diabetic! If I urinate in an uncontrolled environment, my sugar levels will drop too far and I will die!"" The officer, angry now, asks the man. ""Fine then! Get out of the car and walk a straight line! The man in the car says ""I can't do that!"" The officer extremely upset asks the man. ""Why can't you just get out and walk in a straight line?"" The man replies ""Because I'm drunk!""
