The source for the following story is unknown:
In a Peanuts cartoon Lucy demanded that Linus change TV channels, threatening him with her fist if he didn't.
“What makes you think you can walk right in here and take over?” asks Linus.
“These five fingers,” says Lucy. “Individually they're nothing but when I curl them together like this into a single unit, they form a weapon that is terrible to behold.”
“Which channel do you want?” asks Linus.
Turning away, he looks at his fingers and says, “Why can't you guys get organized like that?”
Okay, maybe not the best way to practice unity, but it is a good principle of unity—all individuals submitting to a transcending goal… thus joining together as a single unit.
