[CobraDan]

A group of cowboys were out on the range branding some cattle.
While they were away the new cook saw a sheep tied to a post. Thinking it was for that night's dinner he slaughtered the sheep, and cooked it.
That night after dinner the cowboys were all sulking and ignoring the cook.
He pulled one aside and asked, ..."Did I screw up the cooking"
"No", the cowboy replied, "You cooked up the screwing."
