One day, George Liquor is standing outside of a pet store, watching Ren and Stimpy sleep in the window and gets the idea to adopt them as his pets. Upon arriving home, he introduces them to their new abode: a fish bowl from which the fish was rudely thrown out (and stole George's car as a result). The next day Ren and Stimpy awaken to find George Liquor dressed as a drill sergeant to train them to be proper pets. Their first lesson is house training by doing butt-push-ups on a newspaper. Ren fails, but Stimpy easily does his business while reading about mudslides. He is given a cigar-shaped dog treat as a reward. Next they are taught discipline. To learn discipline, first they have to learn to disobey.
After Stimpy gets out of the shower, he finds that there is not a pair of pants in the house. Ignoring Ren, who tells him that clothes are for humans, and that he doesn't need pants, he tries multiple times to find a pair of pants, without much luck. He is shunned by the outside world because he is nude. He eventually gets lost in the forest, cold, naked, and embarrassed.
Stimpy is making a cartoon when Ren appears and tries to persuade Stimpy that cartoons aren't good for the brain. When Stimpy discovers that Ren is bad for drawing he makes him producer of the cartoon. Ren takes over the credits of the cartoon and Stimpy works in a slavering way until the cartoon is finished and are invited to show the cartoon to Wilbur Cobb, "the godfather of animation".
Ren wakes up feeling younger than ever. He chops enough wood to last Ren & Stimpy an entire year, and saves Mrs. Buttloaves (from the "Firedogs" short). Stimpy announces that it's Ren's birthday, and Ren is disappointed when Stimpy tells him that he is now 10 years old (70 in dog years). Ren ages rapidly, becoming a senile old fart. He decides to retire. During a game of golf, Ren decides to begin looking for a coffin. At his funeral, Stimpy decides to move in with Ren in his coffin.
Hermit Ren: Annoyed by Stimpy's stupidity, Ren goes to live off as a hermit, and goes crazy after months of being alone. He is kicked out of the hermits union for having imaginary friends. Show Segment: Untamed World: Field Guide: Short features Stimpy, reprising his role as a nature show host from Untamed World, in the jungles of Miami, Florida.
