Notes:

My edit based on Professor Poopypants's Name Change-O-Chart 2000 from the book Captain Underpants and the Perilous Plot of Professor Poopypants. The image of Donkey Kong's head is from his snowboarding promotional image from Mario & Sonic at the Olympic Winter Games and Dipper's head in the bottom-right corner is from Gravity Falls short "Dipper's Guide to the Unexplained: Candy Monster". Most of the text comes from existing Expand Dong and Tony Kornheiser's WHY images with a few of them being original cuts from various game covers and other sources.
