A blonde walks into the police station looking for a job. The officer asks her some questions:
Officer: What’s 2 + 2?
Blonde: Ummm… 4!
Officer: What’s the square root of 100?
Blonde: Ummm… 10!
Officer: Good! Now, who killed Abraham Lincoln?
Blonde: Ummm… I dunno.
Officer: Well, you can go home and think about it. Come back tomorrow.
The blonde goes home and calls up one of her friends, who asks her if she got the job.
The blonde replies excitedly, “Not only did I get the job, I’m already working on a murder case!
