It began with me going to the Science classroom of the high school I attended my freshman year. Apparently I wasn't doing the assignment correctly or had arrived late to class and my teacher sent me to this building with a labyrinth-like structure to it. When I went down one of its hallways it led to a room with a teacher in it who was the spitting image of Freaky Fred from Courage the Cowardly Dog. I sat down at the table there and even asked "Are you Freaky Fred?" and at that instant he carved the word "LIES" into the back of my hand with a sharp utensil.
I found out during lunch that this teacher was a nice guy in reality (and looked and acted very much like my boss) and only acted like a sadist when punishing students. The moment lunch ended he snapped back into Freaky Fred persona and we went through various trials that tested my resistance to the pain he inflicted on me. The only one I can remember was when he started to try and tear my fingernails off because I apparently didn't bite them enough.
The dream abruptly concluded with the final battle between Neo and Agent Smith as depicted in The Matrix Revolutions, except it was taking place on the fire escape of an apartment building and they were wearing nothing but their underwear. And it was a hell of a lot better than what the actual film offered.
I challenge all of you to find me a Sayonara Zetsubou-Sensei parody superior to this one:
