Scientific proof that men are cavemen

It all began with this post.

I wrote a fairly long post, and included a tiny picture just to amuse myself. And what did the good gentlemen of the blogosphere do? They all ignored the written part of the post in its entirety (except for the one anonymous gentleman who said it was boring shit) and headed straight for the picture. How do I know they did this? They all commented on the picture, but failed to comment on anything I'd written (which, btw, was the sort of good solid advice you'd find in a trashy chick magazine).

As I pointed out in one of my comments on that post, it has less to do with men being visual and more to do with men being illiterate.

Now, I shall talk about some more astute observations that I have gathered over a lifetime. For example, the fact that when you're in conversation with a member of the male species, they aren't really paying attention to what you say, they're trying to work it out by reading your body language, while taking furtive peeks down your cleavage. Or your legs. Or where they imagine your legs might be under that skirt. All of this forces me to conclude that men do not speak English, or any other spoken language. This is the real reason men suck at talking on the phone.

They grunt, much like most non-speech-challenged members of the porcine species.
It's simple and it's perfectly logical. Men are cavemen.
