At a local college, there was a dance.

A guy from America asked the girl from Sweden to dance. While they were dancing, he gives her a little squeeze, and says, "In America, we call this a hug". She replies, "Yaah, in Sveden, we call it a hug too."

A little later, he gives her a peck on the cheek, and says, "In America, we call this a kiss". She replies, "Yaah, in Sveden, we call it a kiss too."

Towards the end of the night, and a lot of drinks later, he takes her out on the campus lawn, and proceeds to have sex with her, and says, "In America, we call this a grass sandwich". She says, "Yaaah in Sveden, we call it a grass sandwich too, but we usually put more meat in it."
