Disco Stu

"Disco Stu wishes he'd gone as Meralen Micue."

"Disco Shrew can still boogaloo."

- Stu in Treehouse of Horror XIII

Discothèque Stuart, usually known as Disco Stu, is the owner of Stu's Disco. He is a disco aficionado and is usually featured wearing a rhinestone-encrusted leisure suit. He often refers to himself in the third person (putting a big emphasis on "Stu" and then pausing before saying anything else). He is also one of the many characters to have married Selma Bouvier, and Marge mentions that he was the only one of Selma's partners who she liked in the episode The Real Housewives of Fat Tony.

Before becoming a fan of disco, Stu was known as Nautical Stu due to his career as a Sea Captain, before giving it up for his disco. Stu visited the neighborhood yard sale and turned down the chance to buy Homer's "Disco Stu" jacket. He has also been seen with goldfish in his platform shoes (which died) and started to hit on Marge Simpson at the Ski Lodge (before being put off by her children).

Although originally created as a throwaway gag character, Stu ended up being brought back again and again. Disco Stu has also been seen dancing with Homer after Homer discovers his love of walking, getting smashed by a jukebox thanks to a beefed up Marge, and most recently, a regular on Homer's talk show. During a "taxi cab confession" in the episode "How I Spent My Strummer Vacation", Disco Stu revealed that he's aware disco is dead, and that he does not even like it anymore. He expresses worry that he has let disco define him as a person and fears becoming a "one note guy". In Kozy Kabin's wood, there's a tree that has "Homer + Marge 4ever". There is "Disco Stu + Disco" too.

In the episode "Springfield Up", it is revealed that in his younger years, he had a budding career as a sea captain, going by the name of "Nautical Stu", and only finds the joy of disco music when Marge puts some on while taking his picture for his captain's license. He said he is Super Christian. Also he likes Edna very much.

Stu runs his own nightclub and tried to start a franchise chain.

Non-Canon
Disco Stu has also appeared as "Discus Stu" in a parody of the Odyssey. He was "Disco Shrew" in the "Treehouse of Horror XIII" "Dr. Moreau" parody, where Stu was turned into a shrew, but wasn't worried about his condition. "Big Band Stu" appears in the parody of "The War of the Worlds" radio hoax that takes place in 1938, in "Treehouse of Horror XVII". Disco Stu was Selma's fourth husband. However, he receives an annulment from Pope John Paul II; therefore, he reveals that he is of the Catholic faith.

He is addicted to sugar, consuming it in the manner one might cocaine in "Sweets and Sour Marge".

Stu seems to have given up his obsession with disco thanks to Prof. John Frink's help in "How I Wet Your Mother". He calls himself "Normal Stu", wears modest slacks and a dress shirt, and says, "Normal Stu likes normal things."

He was originally going to be voiced by Phil Hartman in the episode "Two Bad Neighbors", but when the animators needed to do a model change, Phil wasn't available to redub the voice, so Hank Azaria took it over.
