A man leaves a bar, gets into his car and drives away. 200 yards further hes stopped by a police officer.

Officer: Good evening sir. Were testing drivers for drunken driving. Would you please blow into this machine?.



Man: Im sorry, I cant do that. I have asthma. If I blow on that machine I will get out of air.



Officer: Please come along to the office and we can give you a blood test.



Man: I cant do that. I have anemia and if you stick a needle in me I will bleed to death.



Officer: Then youll have to get out and walk 5 yards along this white line.



Man: Cant do that either.



Officer: Why not?



Man: Because Im dead drunk!
