Mr. Estiltaph wasn't available for comment due to a bad heart, so I, Axadreary Millafone, will fill in some details.
Dedrick was a poor boy, born without shoes on his feet. He wandered from town to town with a box on his head, like a robot might, if he were pretending to be man. One day, he encountered the spoken word, which came from, you guessed it, a mouth. He would have encountered the written word first, but, the box prohibited that from happening.
Needless to say either world of either word hasn't been the same since he discovered either one, and either will you, now. Happy hunting and I wish you the best of luck removing that ridiculous box from your head.
