Skulls on Mars oh my!

Man, those little green men have funny shaped heads, according to a bunch of nutters who are convinced that the picture to the left here, is of an alien skull on the surface of Mars.
Of course, this begs the question: where's the rest of the body???
Maybe the area used to be a beach and a bunch of little green men were burying a friend of theirs in the sand for fun, when a freak tidal wave came and they had to leave this poor sod in the sand...
Or maybe this guy owed some green gangster a ton of money & so they buried him up to his neck & then let some strange Martian insects eat the flesh off his skull?
And why settle on the idea of little green men? Why not speculate that it's the skull of some ferocious Martian predator that wiped out all other life on Mars, cannibalised on it's own kind and then died off from starvation? All because some clever Martian went back in time to hunt ancient Martian dinosaurs and accidentally stepped on a Martian butterfly...
Sounds crazy right? Then again, so is looking at a rock and calling it a skull!!!
