All Hail Little Rock (PR, you are the man)

Does anyone know why navel oranges have navels? What exactly constitutes a navel? Well... PR can tell you.
I was puzzling over this very question this morning, tossing my navel orange up and down in the air (R was in a meeting all day, or I might have had a target), when Perrin helpfully suggested that I look up "The history of navel oranges" on the internet. Other such searches had been... fruitless... ahem, but nonetheless, I tried again, and lo and behold, discovered that navel oranges are a breed of orange that are seedless but grow a second or third orange within itself at the blossom end of the plant, which forms the navel. So that big piece in navel oranges that looks like another little orange actually IS an orange (see later, the astounding trivia of EW's ...ass, yeah, that's right, ass-tounding). Okay, admittedly it doesn't take a genius to figure that out, but kudos to PR for the good idea that ended my search for the facts about navel oranges. They really are interesting, and ugly. But seriously folks, PR is a useful kid. When R came back into the office, PR and EW were helpfully carrying boxes of mail downstairs, and the village idiot said, "Oh, there goes the box procession!" and laughed uproariously. Dumbass. We got one boy like PR, Gods, why couldn't you grant us two?
