Econ Joke!

Hello, 

So today I was reading the book, "The undercover economist Strikes back", and I came across a joke. I could not help myself but share it here. 

A mathematician, a statistician and an economist apply for the same job.

The interviewer calls in the mathematician and asks, "What does two plus two equal?" 

The mathematician replies, "Four."

Then the interviewer calls in the statistician and asks the same question, "What does two plus two equal?" 
The statistician says, "On average,  four - give or take ten percent, but on average four."
Then the interviewer calls in the economist and poses the same question, "What does two plus two equal?"
The economist gets up, locks the door, closes the shades, sits down next to the interviewer and says, "What do you want it to equal?"

This made my day!
