Breathalyzer Test

A guy is swerving down the road and gets pulled over. The cop says:

- You have to take a Breathalyzer test.

The guy says:

- I can't. I have asthma, and it'll start me on a coughing fit.

The cop says:

- Then I have to give you a blood test.

The guy says:

- You can't. I'm a hemophiliac, and if you prick me, I'll bleed all over the place.

The cops says:

- Then you have to get out of the car and walk a straight line.

The guy says:

- I can't.

The cop says:

- Why not?

The guy says:

- Because I'm drunk you idiot... didn't you see the way I was driving!
