Two I seem to recall, though I am not sure from where,
The Travelling Salesman's Tale.
Story line is the salesman who breaks down near a lonely farmhouse occupied by an elderly farmer with a beautiful wife. They say he must stay the night and after a supper described in great detail,(especially the apple pie) they retire to the only bed in the house, the old man sleeping in the middle. In the middle of the night the old man has to get up to attend to a calving, and at that point come the only two lines I remember clearly:-

She whispered 'Stranger, now's your chance!'
So I went and finished the pie!!!

The other one was the greenhorn in Alaska woo misunderstood the manhood ritual ' Make love to an Inuit woman and shoot a Polar bear',
ending with' Now where's this woman I've got to shoot?'
