Doctor: I'm gonna try something else. Look at these two pictures. One of them is a new ad for Kevin James' new movie The Zookeeper, and the other is a turd in a microwave. Which one is thee ad for The Zookeeper?
[holding up two pictures, both of a turd in a microwave]
Stan Marsh: They both look the same.
Doctor: You don't see any difference in the pictures?
Stan Marsh: No.
Doctor: That is an ad for The Zookeeper
[lifting his right hand up]
Doctor: and that is a turd about to be re-heated.
[lifting the picture in his left hand]
Stan Marsh: They both look like turds about to be re-heated to me.
Doctor: Oh dear. I think I know what this is. You see Stan, as you get older, things that you used to like start looking and sounding like shit, and things that seemed shitty as a child, don't seem shitty. With you somehow the wires have gotten crossed and everything looks and sounds like shit to you. It's a condition called: Being a cynical asshole.
