I, Aye, Eye

As the patch-wearing, homophone-loving scourge of the seas Blewbeard the pirate once said, "Aye, I lost an eye."
What to say about this one? "I" is one of the letters of the alphabet, as well as a name you can call yourself when you're in a hurry. "Aye" is some form of affirmative indication or vote. "Eye" is that ball that plugs one of the holes in the front of your head. True, there are also eyes of storms, eyes of needles, and other such uses for eye – but I'm pretty sure they all derive from the round, centrally placed organ in your face with the hole in it that lets light in.
