This is one of the funniest threads I've read for a long time.
"Dayum GURL you look fine, care to come back to mine for some wine?
"How you doing" And nod my head upwards while smiling. (Look to Joey from friends for example.)
Every play out of the play book, Barney you are god!
But in all seriousness I'd probably take the seat next to them and just use a simple, "Hello, would you like to have a drink with me?"... Then I'd let the magic roll from there.
