Deeper than what you think
Okay, this is a very good movie, and what seems like shallow randomness is actually very deep if you think into it. This man obviously looks deranged. He's gone crazy, I suspect that he must have been laid off from his job which he had put many years into. He is all crazy and he starts living out his fantasies. This is what his deeper most desires are, to start beating shit up, to abuse the cat, shoot laser beams from his eyes, steal beer and give it out to people, and when all the trouble catches up to him, he summons up a heavenly axe and rocks out, making everyone forget what he just did. One can examine this movie from a Freudian approach, I an imagine this guy after going through all this, goes and gives her wife the best sex she's ever had. Sure, it can't happen in real life, but this is what would happen if people were allowed to live out their inner most desires. Isn't that right? *prods the author* I'm sure he had that kind of intent the whole time when he was writing it.
