Rocks don't go in laser guns

Last night when I was trying to fall asleep I was pondering body hair. Some men take pride in having a body covered in hair, I personally do not like body hair. So in thinking of reasons why having body hair is not good (and falling halfway asleep) I came up with this reason:

Overly hairy people remind me of Neanderthals, overly hairless people remind me of aliens. Now in the case of war, who do you want to fix your laser gun, the Neanderthal or the alien? Thats right, the alien. So the less hair the better.

Let me tell you, that was quite funny when I was halfway asleep....not so much now.
