Always thought Greg was the smoothest, being a straight girl myself, religiously devoted to watching every episode ever back in the 70's. However, there's a point to be made that even though some of us are technically straight and have chosen to live our lives mostly that way, we might have had someone of the same sex as our "favorite". I'd take Marcia any day of the week and twice on Sunday, as they say, if I were so inclined. She was dreamy... Greg always looked like he'd be a really good kisser, soft lips, smooth toucher, think I read somewhere that he had an affair with Florence Henderson at the time. Kinda icky, but interesting, to think about.
