A police officer  pulls  over  this  guy  who's  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."

　　"All right, then I need you to come out here and walk this white line."

　　"I can't do that, officer."

　　"Why not?"

　　"Because I'm drunk."
