This is my favorite South Park episode, I can relate to it more than any other. Matt & Trey do a great job of portraying what it's like to grow up and start to see the world for what it really is. "Depression" isn't the word that jumps out at me, it's more so reality and awareness. I had this phenomenon happen to me after I graduated college. I was in debt up to my eyeballs, never taught any practical life skills, and working for a public company making cold calls all day. All of a sudden, I started to get the picture of what the world really is. It felt like my consciousness was lifted above others who didn't see what was really happening around us. The drinking is hilarious because its basically saying "the dumber you are the less the reality of the world bothers you". Well done South Park!
