Goodgame Empire

A blonde girl in year 3 at primary school asks her mother, "why do I have better handwriting than the rest of the class?"
Her mother says, "that's because you're blonde, dear."

Then the girl asks, "why am I the tallest in the class?"
Her mother replies, "that's because you're blonde, dear."

The next day in school her class has a swimming lesson.
The girl comes home and says, "We had swimming today, and I have bigger boobs than the rest of the girls -- is that because I'm blonde?"
Her mother says "no, that's because you're 22, dear"
