Is it Because I'm Blond?

There was once a blond girl that went to Kindergarden. One day, when she came back from Kindergarden, she asked her mom "Mom, other kids can recite the ABC's only up to "F" but I can recite it all the way to "Z". Is it because I'm blond?"

The mother answered, "Yes honey, it's because your blond."

The next day, the blond girl came back from kindergarden and asked "Mommy, other kids can only count up to 13 but I can count up to 100. Is it because I'm blond?"

The mother once again answered "Yes honey, It's because your blond."

On the third day, the blond girl came back from kindergarden and asked "Mommy, other kids are small but I'm as big as my teacher, is it because I'm blond?"

The mother answered "No honey, it's because your 20"
