A blond girl comes back from school one evening.
She runs to her mum and says: "Mummy today at school we learnt how to count.
Well, all the other girls only counted to 5, but listen to me:1,2,3,4,5,6,7,8,9,10 ! That's good, innit?"
"Yes darling, very good."
"Is that because I'm blond?"
"Yes darling, it's because you're blond."
Next day, the little girl comes back from school and
says: "Mummy,today at school we learnt the alphabet. All the other girls only went as far as D, but listen to me: A,B,C,D,E,F,G,H,I,J,K ! That's good, innit?"
"Yes darling, very good."
"Is that because I'm blond, mummy?"
"Yes darling it's because you're blond."
Next Day, she returns from school and cries: "Mummy, today we went swimming, and well, all the other girls have no breasts, but look at me!" She proceeds to flash her impressive 36 D hooters at her mum.
"Is that because I'm blond, mummy?"
Her mother replied "No darling, it's because you're 25."
