A blonde comes home from school and says
“Mummy, mummy, all the other girls in my class can only count to 10 but I can count to 20. Is it because I’m blonde?”
Her mother replies:
“Yes dear, it’s because you’re blonde.”
The next day the blonde comes home from school and says:
“Mummy, mummy, all the other girls in my class can’t recite the alphabet, but I can. Is it because I’m blonde?”
“Yes dear, it’s because you’re blonde”
The next day she comes home and says:
“Mummy, mummy, today we were getting changed for gym class and all the other girls had flat chests but I had these.”
She points to her breasts.
“Is it because I’m blonde?
“No dear, it’s because you’re 25.”
