Pro wrestlers spend a lot of time together. They share rental cars and airplanes, they sleep in the same hotel rooms, they eat their meals with each other, and when they go to work, they do business with one another. Living that lifestyle four or five days week - every week of the year - means that WWE Superstars see each other more than they see their own families. It's a rough life to be sure, and just like regular people may bicker with those closest to them, wrestlers are likely to butt heads when they get frustrated. Unfortunately, sometimes it doesn't stop there. Some wrestlers are notoriously hard-headed and temperamental, and all of them are used to physicality. Sometimes, push comes to shove, and two men settle their issues (or more likely, fail to do so) with violence. Stories get around - especially with the preponderance of "shoot"-style interviews in today's day and age - and so very little is kept as proprietary information. Here are 10 of the most notable real-life fights that broke out between top-level wrestlers. These brawls resulted in lost pride, lost jobs, and very nearly lost lives. If nothing else, hopefully the combatants all learned valuable lessons from their skirmishes.
