Self-sufficiency can be achieved with minimal effort. Take for example the fable of the fireman and the *******. "Boy, it sure is hot in here!" The fireman said as he pulled out his hose. "It sure is!" The ******* answered back. "Have you been a ******* for a long time?" Bill, the fireman asked. "Thirteen years," Jill, the ******* answered. "Hey, that's a coincidence. I've been a *******, I mean fireman, for thirteen years too!" Bill exclaimed with a big *******, I mean smile, on his face.
