OK, one more....
A farmer has a sow who is about to give birth. While monitoring her, he realizes that his out of iodine to dip the piglets' navels in. He wants to run to town to get some, but doesn't want to leave the sow unattended. He has a friend from the city visiting them at the time, so he asks the city guy to watch the sow while he's gone.
While he's gone, he realizes that he forgot to tell his city friend to make sure the piglets stay away from the sow's snout for a while. (For those of you who didn't grow up around pigs--after giving birth, most sows eat their placenta and afterbirth. However, for reasons not entirely known, some--not many--sows will also eat the piglets if allowed. It's suspected that the sows smell the piglets, which still smell like the placenta at that time, get confused, and eat them.) But he decides not to worry about it--surely his friend will realize what's happening and stop this if it occurs.
When he gets home, he goes out to the hog barn--and just as he is approaching the sow's pen, he sees a newly born piglet get up on its legs, take its first steps toward its mother's head--and get eaten in one chomp.
Horrified, he yells out at his city friend, "How could you let that happen?!?"
"Oh that. Don't worry about it!", replies his friend. "That piglet's been through her seven times already, and still doesn't have a scratch!"
