After thinking about this, I can give you a "compare-and-contrast" between men and dogs.
A scientist and his dog are out for a walk. They come upon an unusual object. Here is how they think:
Man: Wow, I've never seen this before. It's really weird. Maybe I can sell it to someone. No, better still, I'll put together a research team. I'll apply for a government grant to study this object. Maybe I can work in a field trip or two so that I determine frequency of occurrence, see if I can find another one. This might be quite a lucrative find, not to mention prestige if it turns out to be unique. Plus the possibility of adding to our body of knowledge. Heck, that's worth a couple of publications at least. Maybe more. Man, I've got a thousand questions to be resolved with this object. This is great.
Dog: <sniff><sniff>
Hmmm.... can I eat it? No, doesn't smell too good.
OK,... can I have sex with it? Nope, doesn't smell at all like a dog.
Well,... can I play with it? It's kind of just lying there. Probably not.
Okey dokey, piss on it. <hike hind leg>
Side note: People walking up to the dog fall into the "can I play with it" category.
