You have to wonder, did the whole neighborhood give Dexter their property so he could build this gargantuan underground laboratory? What was he funded with, their rent? And also, his lab (according to one episode in which he gets lost in the dark, ancient recesses of his laboratory) is so large it might as well have its own zip code. And another thing, how did American parents give birth to an American girl and a German boy? Was Dexter adopted?
Oh forget, who cares. It's a whoop-ass show.
