Your mother! (sorry am in a silly mood and can't help myself) A blonde goes into an electrical shop and says to the man at the till "I would like to buy that TV over there" The man at the till says "Please leave, we don't serve blondes" The blond waits a few days for the original till man to be away and returnes again asking to buy the TV. Again she is told "we don't serve blondes". Then the blonde has a great idea. She dyes her hair brunette and wears some large sunglasses so they won't recognise her face. Confident that she will get her TV this time she marches up to the desk and says "hello, I would like to buy that TV over there" The man looks at her and says "for the last time!, WE DO NOT SERVE BLONDES!" "How did you know I am blonde?" she asks to which the man replies "Simple, That's a microwave"
