- "Pray... For... Mojo..."
- ―Mojo typing
Mojo was Homer Simpson's helper monkey who eventually adopts Homer's unhealthy lifestyle and becomes very obese.
Always in search of new ways to be more lazy, Homer decides to use his enfeebled father (who thought he was getting the monkey to eat it) in order to qualify for the services of the highly trained and intelligent Mojo, whom he basically intends to use as a Simian slave. Mojo, however, soon realizes this—as well as the fact he prefers Homer's sedentary lifestyle to the job he has been trained to perform. In one incident, Homer sends Mojo to steal donuts from the shop and bring them back to him. Mojo steals the donuts, but then eats them himself, which leads to a scolding from Homer.
All the donuts and other aspects of Homer's lifestyle soon take their toll on Mojo, and he becomes bloated and lethargic. Because of poor health of Mojo, Marge becomes upset with Homer, who tries to show her that Mojo is still agile with a pathetic dance by the monkey that ends with Mojo wheezing and collapsing. Seeing he is no longer of any use and not wanting to have to potentially answer for a dead monkey, Homer returns Mojo to the lab, dropping him off anonymously at the door. The Lab attendant, alarmed by Mojo's condition, hands him a keyboard to type what was wrong. He enters "Pray... For... Mojo!"
