Mental_floss takes a closer look at pigs in this week’s List Show. Why pigs? Because every time someone mentions pork, they have to put money in the piggy bank, and it’s time to fill the bank to finance a party. But there have been some pretty interesting pigs in our history, and fascinating facts about our delicious porcine livestock. And since it’s April Fool’s Day, they thought it would be nice to have a really silly subject. Still interesting.
