I remember this being discussed awhile back. Am I thinking of the wrong game?
Looks like he is supposed to be Clint Eastwood, by his face on the promo posters. Or Chuck Heston. Got dat "line" mouth and the glarey eyes! Besides, BIOSHOCK 1 SPOILER AHEAD... You played the villain all along in that game, maybe Booker turns out to be the same. Clint Eastwood's chair yelling racism fueled jibber jabber falls inline with Comstock's world.
You're thinking of his adopted great-grandson Howard, who always goes around introducing himself by singing "THIS IS HOWIE DEWITT!".
Because of this, he is greatly disliked. But deep down, everybody knows that they would do the same thing if their name was "Howard DeWitt". Find out more in my upcoming fanfic, "Songbird Something Something Ponies". Also, keep an eye out for my YouTube video which supercuts a bunch of scenes of Elizabeth emoting while "Crawling" by Linkin Park plays in the background. I'm not saying I'm an artistic visionary, but I'm totally an artistic visionary.
