Lincoln Square Puns

A clown walks into the police department looking for a job. The officer wants to ask him a few questions.

Officer: What’s 2+2?

Clown: (counts on his fingers) … 4!

Officer: Good.  What’s the square root of 100?

Clown: (thinking fiercely) … 10!

Officer: Very good! Now, who killed Abraham Lincoln?

Clown: Ummmm … I don’t know.

Officer: Well, you can go home and think about it. Come back tomorrow.

The clown goes home and calls up one of his friends, who asks him if he got the job. The clown says, excitedly, “Not only did I get the job, I’€™m already working on a murder case!”
