Undone by delicious but bizarre run-in with the law
June 24, 2010
A few weeks ago, I had a bizarre but delicious run-in with the law that in retrospect seems dreamlike more than actual, and has all the delirious precision of a perfect comic nightmare. It happened to me and, therefore, it offers my memory a delicious sip of surrealism to soothe the rough touch of the prosaic.
The cops pulled me over for being unroadworthy because my ancient Corolla sedan resembled the end of the world on bald tyres. As well as that, the boot didn’t close and the headlights were permanently on high-beam. I used to enjoy blinding all the junkies in Smith Street on my way home from Safeway.
The incredibly beautiful policewoman smiled at me in a kind of pitying way and said I looked a bit downShe gave me a card with a special number upon it.
”You do look a bit down. This is the toll-free number for Lifeline if you’re happening to feel like suicide. Why not give them a bell?”
She poked a huge torch in the car and I saw it in an entirely new way. She found half a kilo of offshore liquorice allsorts in the dashboardShe failed the car on frayed nylon seat coversShe failed it on many things in the end, including a rear quarter-panel with a great big gouge in it that was put there by a mad driver because he felt like it.
She swiftly glued a canary yellow certificate on my windscreen and part of me died.
Her companion was a policeman seven-feet high who said nothing the whole time the interview took place. I smiled up at him at one stage and said very sweetly: ”How you going, mate?” He seemed not to be my mate, for he pushed an invisible button in his right shoulder and a second police car arrived within a minute. He called for back-up on an unroadworthy car!
I shouldn’t have called him mate; that was very much an oversight. The second police car screamed to a standstill right next to the first one; I noticed it was on high-beam just like my car because there’s something wrong with the dipswitch.
In the end, the handsome policewoman allowed me to carefully drive my car home, where it now languishes in sheer disgrace out the front.
