You make a good point about Heather... just take a moment, close your eyes, lean back and imagine what a 4-armed woman could do.
Exactly. It amazes me that they can even make an alien woman with a pig snout attractive, much less a knockout like her. The hair, body, jacket, voice, arms and hands all do it for me.
Between Leela and Amy, I'd go with Amy. Her personality works better for me personally (Leela would think/know that I'm an obnoxious idiot, while Amy is easy going and fun)...Amy also has a cute face and a sexy bod.
Oh, and a ton of cash and no deformations and actually gets around probably less than Leela (though it would be great to be with a girl who could snap anyone's arm in half if they mess with you).
