Why should you masturbate to that one chick from Mythbusters?
She's a woman. Who does science. As we all know, this is suspension of reality. Tits + rockets = Nipples in the stratosphere. Boobs in the sky. B-Cups in the clouds. Without gravity, imagine how they would look.
edit She wears plaid
It's like a lumberjack, without all the disgusting hair on the chin. With a vagina. Who wouldn't want to fuck any of the members of Monty Python?
edit She likes to blow things up
If she can blow up a car that efficiently, imagine what she can do with fellatio.
