Hibbert Moneymaking Organization is a new "HMO" opened by Julius Hibbert.
In "The Last Temptation of Homer", Bart starts to have difficulty seeing properly. Marge then takes him to the Hibbert Moneymaking Organization, where Dr. Hibbert asks if they have insurance. After he asks, a tube similar to Charles Montgomery Burns' lowers over Marge, but she says she does and he withdraws the tube - it may have lead to the same Arabic Palace Charlie went through earlier in the episode. Dr. Hibbert admits them to the Optometrist.
