Simpsons, The Easter Egg - Bongo

Firstly you'll have to watch the episode where the Comic Book Guy has a heart attack.
During the first few minutes of the episode you'll see Bart and Milhouse get a $50 bill and they'll go around spending it etc. Toward the end of their spending spree they decide to go to the Androids Dungeon (the comic shop) and buy an expensive comic book. It is Radioactive Man 1000. They only have somethuing like $10 but it's $25. Then the Comic Book Guy tells them about how special it is. He tells them that it is splash proof etc. He says that if you spill any liquid it splashes off onto lesser comics. It shows the Comic Book Guy pouring Coke or something onto Radioactive Man 1000 comic. It then shows the Coke splashing off it onto another lesser comic with the title BONGO. Bongo is the name of the comic distributer that the Simpsons use for their comics!
