A joke

A blonde was complaining to her friend about constantly being called a dumb blonde. Her friend tells her" Go do something to prove them wrong! Why don't you learn all the state capitals or something?" The blonde thinks it is a great idea and locks herself up for two weeks to study. The next party she goes to, some guy is making dumb blonde comments to her. She gets all indigant and claims," I'm NOT a dumb blonde. In fact, I can name ALL the state capitals!" The guy doesn't believe her, so she dares him to test her. He says" Okay, what's the capital of Australia?" The blonde tosses her hair in triumph and says,"That's easy! It's A!"
