A cowboy was riding accross the plain when he heard shouting from a nearby house. So he went over to investigate and after searching the house, found a young maiden lying naked in bed, with her four limbs tied to the bed corners.
"Oh thank god" she cried: "you have got to help me, two men came by and killed my husband then took it in turn to ravish me before stealing all our money, help me please!"
The cowboy thought for a second, then as he unzipped his fly and took down his trousers he said: "Maam, this just aint your lucky day!"
