Field Sobriety Test

A police officer pulls over this guy who had 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.

- Alright then I need you to come out here and walk this white line.

- I can't do that, officer.

- Why not?

- Because I'm too drunk to do that!
