Blond Cop Joke

A blond walks into a police station looking for a job.  She asks the cop sitting at the front desk if they would be able to hire her for a position.  The cop says "Sure, if you can tell me who shot and killed Abraham Lincoln."  The blonde runs out of the station and calls her friend excitedly.  Her friend asks if she got the job.  The blond replies, "Not only did I get the job, but I'm already working on a murder case!"
