This wasn't precisely a pick-up line -- more like a Pickup line, as in Chevy Pickup -- but when I moved to Wyoming three years ago I saw this line in a singles ad: (I just happened to glance...)

"Looking for a ranch-raised woman. Hay bales no problem."

Which I took to mean that she should be able to lift hay bales without difficulty. Maybe it meant he'd have no problem with it if she brought her own hay bales ...
