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.
