A blonde walks into a police station looking for a job. An officer decides to test her with a few questions.

Officer: “What’s two plus two?”

Blonde: “Ummm… four!”

Officer: “What’s the square root of one hundred?”

Blonde: “Ummm… ten!”

Officer: “Good. Now tell me… who killed Abraham Lincoln?”

Blonde: “Ummm… I don’t know.”

Officer: “Go home and think about it. Come back tomorrow.”

The blonde goes home and excitedly calls one of her friends.

Friend: “Did you get the job?”

Blonde: “Not only did I get the job… I’m already working on a murder case!”
