The pair induct a teenaged girl named Susan Fout into their fan club after she brings them one million dollars in small change and says the oath. In a short, Ren and Stimpy go to their secret lair in the lower/large intestine of a sperm whale. With each letter, Ren begins to become more angered and jealous at Stimpy for the attention he is receiving and the insults he is getting. However, he tries to uphold his promise to Stimpy and is forced to write back kind letters. The episode continues, with Ren continuing to read fan mail, in which more fans see Stimpy in a positive light and see Ren in a negative light. Ren feels guilty and ashamed of how he cruelly responds to the boy with the bed wetting problem instead of helping him, and tries to get Stimpy to stab him with a rubber knife as punishment, but Stimpy decides that Ren has learned his lesson. Ren wants to keep that a secret from everybody and hopes nobody heard that. Stimpy reads it and says that Ren should feel ashamed, that a lot of kids have a problem like that and reminds Ren that they still both wet the bed sometimes.

Later, after a boy admits to wetting the bed and asking for advice, Ren is disgusted and writes back an angry letter saying he is going to tell the boy's friends not to come over to his house ever again because of his bed wetting. At first, Ren likes the idea, but begins to abuse this privilege after a child insults him in her letter by asking why Stimpy always puts up with Ren's abuse and if he's a mosquito, by writing passive aggressively to her that Stimpy isn't real and that she's stupid.

As president, Ren's job will be to read all of the fan mail and reply to it as Stimpy. Ren becomes distraught, so Stimpy decides to make Ren the president of his fan club in order to cheer him up. Piles of fan mail arrive, all of it for Stimpy and none of it for Ren. The episode begins with Ren and Stimpy waiting patiently for the mail. When Stimpy receives the adoration of many fans, Ren becomes jealous, so Stimpy makes him the president of Stimpy's fan club to solve the problem.
