To me, ATHF is like Tim and Eric's Bedtime Stories. It's meant to scare you in some way. Like there's actually real people that f**ked up out there.
This episode is called "Dickesode". And that guy is named Mr. Wongburger. His parents are cheeseburgers (if I recall correctly), and he goes into a rant about how they had wanted him to be born a cheeseburger, instead of a giant dick. I'm paraphrasing. :{
