Here's one of those little pieces of useless knowledge that you may never actually need. Be sure though, should you ever be put in a life or death situation dependent on you making a pig's tail go from curly to straight, you'll be glad you spent 52 seconds watching this video.

We all know that pigs have corkscrew style tails, but little did we know that with just one simple move, they can straighten it out and be like almost any other animal. Luckily, this guy knew the trick and decided to share it with the world.

Be careful with your newfound knowledge. With great power comes great responsibility.
