What is the perfect pick-up line?

The other day, I was minding my business, buying some ginger ale for a sick friend at the corner grocery store.  The guy who was checking me out (no pun intended)--probably half my age--must've called me "sweetie" and "honey" about 15 times in the 2 minutes that I interacted with him.  I was not feeling particularly hot at that moment, a little sweaty post-yoga still in my yoga clothes, and carrying about 30 pounds of groceries in a backpack from the local produce store.  I wasn't sure whether to be flattered or insulted.  And being "post-yoga" I retained my calm and thoughtful composure as I left the store.

But it started me thinking--what is a nice way to be hit on or picked up or complimented?  And what makes me feel demeaned?  I feel men have a lot to learn from this conversation, so I hope some of you are reading!  And I think I am probably representative of most women, but women feel free to chime in too...

Things that make me fume:
1.  Whistling or cooing at me from across the street.
2.  Hissing at me (this is worse than #1)
3.  Calling me "mamacita."
4.  Following me around, especially when I've told you to go away.  (This is especially scary when I'm in another country; for example India).


Things that make me go hmmm....
1.  "Honey," "sweetie"...
2.  Staring at my breasts while talking to me.
3.  "Are you married?"  Now why is this the first thing a strange man would ask me?
4.  Brushing up against me "accidentally..."

Compliments that every girl doesn't mind:
1.  "You're beautiful." (said in a sincere tone of voice without any aspects of the first list included).
Actually, the nicest compliment I have ever gotten was when I was minding my own business shopping at Walgreens and a man walked by me and said,
"Can I tell you something?"
"Sure," I said.
"I just want to tell you that you are absolutely gorgeous.   I was walking by and just noticed."
"Thanks," I said, blushing crimson red.
And that was it.  No asking me out, nothing further.  That comment made my day, my week, my month...you get the point.
2.  "You have a nice smile."
3.  "You have beautiful eyes."
4.  "You have nice energy."  This must be a San Francisco hippie touchy-feely thing, but this line once got a guy at a gas station my phone number.

So layer on the compliments, hit on us--we like it--but especially when it's done in a classy and sincere manner...
