I heard a different version:

Young farmer: I got some pigs, but I don't know what to feed them. What do you feed your pigs?

Old farmer: I had some pigs once, I fed them one of my cows that had died of consumption.

Young farmer: Really?

Old farmer: Yup.

<2 weeks later>

Young farmer: One of my cows died, so I fed it to my pigs. They all died. Your pigs really thrived on meat of a diseased cow?

Old farmer: Nope, my pigs died.
