Free Lunch

It's supposed to be a fundamental principle of economics that there's no such thing as a free lunch.

I beg to differ. While I'm changing employers, folks from my old company are taking me out to lunch to say good-bye, and folks from my new company are taking me out to lunch on my first day to say hello.

So, I've already figured out this scam. All I have to do is change employers every other day, and I'll never have to pay for lunch again!
