Damn, that's nuts. But what is a pen test?

That reminds me of when I was smoking out of my pipe and driving down the road, and I had just taken a hit when I saw a cop flick on his lights and start following me. So I shove the bowl between the crack in the seats, turn to my friend and say, "Jay, give me one of your cigarettes." So I light it real quick and suck down like half the cigarette in one puff to get rid of the smell. The pig tells me that one of my headlights is out, and asks me if I'm feeling okay. I take a puff of the cigarette and say, "Of course I am alright, officer." And then he says, "Ok, you have a safe drive home, you hear?" I reply with, "Certainly sir" and then get back into my truck, pull the bowl out, and pack a celebratory bowl.
