It's funny that as a girl, I can't stand corny "pickups", but doing the same thing to guys always gets their attention.
The other night my best friend and I we were at a party, and she asks these 2 gents, "Are you guys swingers?" They perk up and come over in a hurry, "woah! okay, okay! umm, what, you and your girl into that kind of thing? Umm.. how does this usually work out?" As if we were REALLY serious...

She goes, "I'M talking about the swings outside the apartments... what were YOU thinking?"
lol... so we all enjoyed a nice little moonlit chat on the porch swings outside. A little laugh goes a long way.
