This one is great for the "well indowed" flight attendants that are much more beauty than brains.

Turn the little overhead map light on as low as you can get it. Tell your flight attentant it is a telescope that you use for navigation. Tell her the moon looks really pretty tonight and ask if she would like to see it. You will get a free lap dance. And to add to it, tell her to turn the little ring on it to focus it. She will be seeing spots for a while when it goes to full bright.
