A young blonde female stock broker was bored with driving her BMW. It lacked individuality and besides that, every other girl in the office had one. She fancied something a bit more individual, perhaps an MG sports car. That week she visited her local car dealer and spied a beautiful Jaguar XK140 convertible. It was wonderfully restored and she fell in love with it's gorgeous red paint job. Soon she was tearing down the leafy country lanes enjoying her beautiful new car. Her long blonde hair was flowing in the wind, music blaring from the radio, what could possibly go wrong? At that thought there was a splutter from the engine and the car slowly coasted to a stop. She got out and lifted the bonnet and concluded after a few minutes that she didn't have a bloody clue what was wrong. Luckily she had her mobile phone with her and a quick phone call to the AA and a short wait saw a bright shiny yellow van pull up behind her. "That's a lovely car," said the mechanic. "What seems to be the matter?" "Well, it just conked out I'm afraid." "Let me have look." He set to work and ten minutes later the engine was purring like a cat again. "Thank goodness," she said. "What was the matter?" "Simple really, just crap in the carburetor," he replied. Looking shocked she asked, "Oh, OK ... how many times a week do I have to do that?"
