That guy was just all buzzed up on the caffeine from drinking all that Dew and had to burn off that energy someway. Plus his wife had been nagging him about going out and getting a tree, and this seemed easier.
Holy Frap! I have to go to the bathroom after just SEEING that much Dew. That guy will be ready to take the tree down right after the holidays. After all, he will probably still be awake in January!
