"Okay, so I came over here to ask you to dance, but I'm kind of concerned. I mean, we could hit it off really well, end up having a few drinks, next thing you know you're giving me your number because I'm too shy to ask for it, I finally get up the nerve to call and we take in a movie, have some dinner, I relax, you relax, we go out a few more times, get to know each other's friends, spend a lot of time together, then finally have get past this sexual tension and really develop this intense sex life that is truly incredible, decide our relationship is solid and stable, so we move in together for a while, then a few months later get married, I get a promotion, you get a promotion, we buy a bigger house. You really want kids, but I really want freedom, but we have a kid anyway, only to find that I am resentful, the sparks start to fade and to rekindle them we have two more lovely kids, but now I work too much to keep up with the bills, have no time for you, you're stressed and stop taking really good care of yourself, so to get past our slow sex life and my declining self-confidence I turn to an outside affair for sexual gratification. You find out because I'm careless and a lousy liar, you throw me out (justifiably so) and we have to explain to the kids why mommy and daddy are splitting up. That's just too sad. Think about the children. For God's sake, if you dance with me and we hit it off, let's just keep it sexual, because we both know where it's going."

This one, applied correctly, may actually have a prayer on the "laugh and talk" angle

What's your name? That's a beautiful name. Can I ask you one single, impulsive question? Are you in love at the present moment? I'm not the type of guy to impede on another man's happiness but if the answer is "No" I'd like to continue with my rhapsody. Has anybody ever told you that you glide? (What?) It's a very special quality, every other girl in this place merely plods along but you glide, girls who glide need guys who make them "thump." (What's thump?) You think about him, you can't eat, you can't sleep, you watch the phone waiting for it to ring. Girls who glide need guys who make them "thump," I can make you "thump." Have dinner with me.
