Nothing better than an intense rivalry between scientists...right? Well, that's exactly what happened with paleontologists Edward Drinker Cope and Othniel Charles Marsh -- two men who really take the cake for petty feuds. This fight, also known as The Bone Wars or The Great Dinosaur Rush, was so heated that it devolved into bribery, theft, and destruction that almost ruined paleontology. Uh, yikes!
