A scouser walked into the local job centre, marched straight up to the counter and said 'Hi, I'm looking for a job'.
The man behind the counter replied 'Your timing is amazing. We've just got one in from a very wealthy man who wants a chauffeur/bodyguard for his nymphomaniac twin daughters. You'll have to drive around a big black Mercedes and wear the uniform provided. The hours are a bit long but the meals are provided. You also have to escort the young ladies on their overseas holidays. The salary package is £200,000 a year'.
The Scouser said 'You're bullshitting me!'
The man behind the counter said 'Well you started it!'
