"Well, that depends on what you mean by disproportionate. The [penis] isn't a muscle, so it doesn't grow in relation to the shoulders, say, or the pectorals. You can't make it bigger through exercise, that's for sure... women have told me they're curious about its size--you know, outgoing chicks who're just trying to be outrageous or horny. I hear all kind of lines, including 'Oh, you're hurting me; you're so big.' But it means nothing. Bodybuilders' cocks are the same size as everyone else's."
-- Arnold Schwartzenegger, in Oui Magazine in 1977, to interviewer Peter Manso, when asked if his penis was disproportionate to the rest of his body. From TheSmokingGun.com
