How to Open a Wine Bottle Without Using a Corkscrew

What do you do when you have a bottle of wine ready to uncork, but no corkscrew on hand? 

Grab yourself a towel (or any cloth that you can wrap around the wine bottle), stand near a sturdy vertical wall or tree, and start hitting the bottom of the wine bottle in rhythmic and even thumps against the flat vertical surface until the pressure of the wine against the cork nudges the cork far out enough for you to pull out with your hands or a set of pliers. Yep, it's that simple.
