Greg Gutfeld writes this in The Bible of Unspeakable Truth.
For the next week, do your job drunk. If your performance stays the same, you don’t lose any limbs, and no one notices you’re soused, then your job is not real. But if your performance suffers, and you lose a limb, then congratulations-you have a real job and you actually contribute something worthwhile to society. You should be proud, even if you’re dead.
