Doug was the first Nicktoon greenlit for production in 1991. The agreement gave Nickelodeon the right of first refusal for 65 episodes, broken into 13 episodes every season. Nickelodeon produced 52 episodes, but declined to pick up the option for the final 13 episodes due to a budget freeze at Viacom in 1995. Jinkins began shopping the show around to other networks, with Disney deciding to purchase his production company, Jumbo Pictures, outright. As a part of the agreement of Doug moving over to Disney, Nickelodeon retained the rights to the 52 episodes produced between 1991-1994.
The Funnies' neighbors are the Dinks. Their name stems from the acronym D.I.N.K. which stands for "double income, no kids". This is a slang term that refers to a childless couple where both people work and are, therefore, more affluent than families with dependents.
The origin of the character Patti Mayonnaise is the combination of the names of two girls Jim Jinkins had a crush on in school.
In the episode where Doug and Skeeter form a garage band, they wear oversized suits to a gig at a birthday party, a homage to the Big Suit worn by David Byrne of the Talking Heads in Stop Making Sense (1984).
The name of Doug's unseen principal, Mr. Buttsavich, was the name of Jim Jinkins' elementary school principal.
