Spark plugs

From the Best of Craigslist --- which is an all-around great way to waste some time --- Hey, Crackhead.

On Wednesday morning I emerged from my girlfriend's building by U.N. Plaza to find that you had sawed the tops off both the sparkplugs on my motorcycle. At the time, I had no idea why anyone would do that. Other than the sparkplugs, the bike was untouched. Some kind of bizarre vandalism? A fraternity prank gone awry? I had no idea. All I knew is that I looked like a huge douchebag riding the Muni to work in a padded motorcycle jacket and helmet.

Because the bike was immobilized I got a $35 street sweeping ticket that night. Thursday I had it towed to the shop ($45) where they replaced the sparkplugs and the boots ($50 including labor). They explained to me that "people" - I use the term loosely here - like you break off the tops of spark plugs and use the porcelain tubes to smoke crack. As an engineer and former MacGyver fan, in a way I think this is kind of cool. But then I remember that I just paid $100 for YOUR crackpipes, and I get angry again.

What I don't understand is,

YOU ARE A CRACKHEAD. WHY DON'T YOU OWN A CRACKPIPE?

I am an engineer. Do you ever see me shaking down bums in the Loin for a calculator and sliderule? No, you don't. Because engineering is the main thing I do, I went and bought myself a calculator. The main thing you do is crack. How do you get by without a crackpipe? The other crackheads must clown on you non-stop. I mean, the fucking saw you used to saw off my sparkplugs is probably worth five or ten bucks. Why not sell or trade it for a crackpipe? You really haven't put much thought into this, have you?

I know the feeling. I know the feeling exactly.
