At a local college dance in Sweden, an American asked a local girl to dance.
While they were dancing, he gave her a little squeeze, and whispered, "In America, we call this a hug."

She replied, "Yaah, in Sveden ve call dis a hug, too."
A little later, he gave her a peck on the cheek. "In America, we call this a kiss."

She replied, "Yaah, in Sveden ve call dis a kiss, too."
A few drinks later, they moved out to the campus lawn and had sex.

"In America," he told her, "we call this a grass sandwich."
She replied, "Yaaah, in Sveden ve call dis a grass sandwich, too, but ve put more meat in it!"
