I liked the part about how women leave men when they find a better mate less, though. Although I agree a lot of people do that (male or female, really), it bothered me a little bit that it kind of sounded like he was saying "that's their way of not being monogamous" when the way I see it, leaving someone to be with someone else is being monogamous, since you're only with one of them at a time.
I liked how he talked about the bus and animals, too. I liked it less when he commented that he was never approached by attractive women.
My favourite poly-related sentence was the same as you guys, but he's being a bit polier-than-thou there. Some people ARE monogamous, it doesn't make them bad people, I don't think.
