Kai: The Hatchet-Wielding Hiker

Kai, also known as Caleb McGillvary, saved a woman's life with his lucky hatchet. In his viral video, the hitch-hiking free spirit goes on a long ramble about a man that gave him a ride. The driver admitted to raping a young girl, believed that he was Jesus Christ, and proceeded to run his car into another truck and attack a pedestrian woman. Good thing Kai and his hatchet were there, because he stopped the man from hurting the woman any worse. The highlight of this video is definitely Kai's describing his life-saving deed. "Smash, smash, sa-mash!"

Bird Sings Dubstep

Dubstep has slowly taken over: It even leaked into Taylor Swift songs this year. Still, it's surprising that a pet bird was able to catch on to the trend. Will this cockatiel do a collaboration with Skrillex in 2014? Only time will tell.
