Why would I make a crack about my head?
Oh, you mean because it's large, big, behemoth, Brobdingnagian, Bunyanesque, colossal, cyclopean, elephantine, enormous, gargantuan, giant, gigantesque, gigantic, herculean, immense, jumbo, mammoth, massive. See also: mastodonic, mighty, monstrous, monumental, stupendous, titanic, tremendous, vast, walloping.
Yeah, now that I think about it, that would be a good way to stick out. Thanks for the advice, Melanie!
