Sir, will you breathe into this please?

I have a cousin in Arizona who was pulled over the other day because he swerved a little on the road. He was really tired from working and was looking for place to pull over and rest a little.

The cop who pulled him over asked him if he had anything to drink.

"No. Not a drop," my cousin answered.

The cop didn't believe him and brought out a breathalizer test. He asked him to breathe (exhale) into the machine. (Keep in mind that my cousin looks like he's 18.)

My cousin said, "Sure."

It registered zero.

The cop asked him, "Sir, are you okay?"

My cousin said, "Yeah, I'm just really tired from work. I was looking for a place to pull over and slap myself awake."

The cop asked him, "Do you need me to follow home and make sure you make it back okay?"

My cousin answered, "No. That's okay. You pretty much scared the living shit out of me. I'm wide awake now. Thanks."

The cop chuckled as he let him go.
