 A primary teacher starts a new job at a school on Mersyside and,
trying to  make a good impression on her first day, explains to her class
that she is a Liverpool fan. She asks her students to raise their hands if
 they, too, are  Liverpool fans. Everyone in the class raises their
hand expect one little girl.

 The teacher looks at the girl with surprise and says: "Mary, why
didn't you  raise your hand?"

 "Because I'm not a Liverpool fan," she replied.

 The teacher, still shocked, asked: "Well if your not a Liverpool fan,
 then who are you a fan of?"

 "I'm a Manchester City fan, and proud of it," Mary replied.

 The teacher could not believe her ears.  "Mary, why, pray tell, are
you a  City fan?"

 "Because my mum and dad are from Manchester, and my mum is a City fan
 and my dad is a City fan, so I'm a City fan too!"

 "Well," said the teacher, in a obviously annoyed tone, "that's no
reason for you to be a City fan. You don't have to be just like your parents
 all  the time. What if your mum was a prostitute and you dad was a
drug dealer and car thief, what what you be then?"

 "Then," Mary smiled, "I'd be a Liverpool fan."
