MY COMMENTS:

Oh, you can have a lot of fun with this one.

I have a good friend who can't drive up next to a woman
without flirting. He likes to "waggle his eyebrows" at
every woman he sees.

Next time you're next to a cutie, waggle your brows
and wave. When she smiles, make the old fashioned motion
of rolling down your window to her, and roll down yours.

Finally, take out your cel phone, point to it, and say
"What's your number?"

I've done variations of this myself, and had some great
fun success with it.
