All the way back to the Founding Fathers, government offices were a fine place to look for humor material. A simple, “Where’s the restroom?” was good for an instant 600 word column you could sell for some mad money.
Running this country is so serious that, from time to time, the government needs some comic relief. I believe this is the reason for the Transportation Security Administration.
