CharacterKarlBehind the scenes
An impeccably turned-out secretary, an unforgettable husky voice and boundless devotion. Karl appears only in "Simpson and Delilah" (season 2, 1990), but there he becomes the most competent person at the plant: he hires himself out to a newly promoted Homer, saves his wedding anniversary with a singing telegram, then takes the blame in his place to spare him the sack. Here you will find Harvey Fierstein's voice, the actor's refusal to be drawn in his own likeness, and the anagram hidden behind Dimoxinil.
Tall, blond, impeccable and blessed with a voice you don't forget: Karl is the secretary who made Homer Simpson, for the space of one episode, a respected man.
A character with a single appearance — and yet one of the show's most endearing. A profile.

Who is Karl?
Karl is Homer Simpson's secretary and personal assistant at the nuclear power plant. He comes on the scene when Homer, freshly restored to a full head of hair, is promoted to junior executive by Mr. Burns.
The character has only that first name: no surname is ever given to him. Watch out for the classic trap: Karl, with a K, has nothing to do with Carl Carlson, Homer's colleague.
His distinguishing feature? He is by far the most competent person in the whole establishment — and he puts that competence entirely at the service of a man who deserves nothing of the sort.
"Simpson and Delilah"
The episode, broadcast in 1990, starts from a swindle: Homer obtains an outrageously expensive baldness treatment through insurance fraud at the plant. With hair, he is promoted at once.
Karl then installs himself as his secretary, and turns the dunce into an executive: he coaches him, redresses him, feeds him his lines. When Homer forgets his wedding anniversary, it is Karl again who saves the day by having a singing telegram delivered to Marge.

Karl's sacrifice
The fall comes from Waylon Smithers, stung to see his own loyalty ignored: he investigates and uncovers the insurance fraud. Karl, rather than let Homer down, takes the blame in his place and is fired.
The finest part is still to come. On the morning of Homer's big speech, Karl comes back — with a prepared text — to assure him that his successes owed nothing to his hair, and everything to his will. A scene that made the character a lasting favourite with viewers.
Harvey Fierstein behind the character
Karl's voice is that of Harvey Fierstein, an American actor and playwright with a uniquely husky voice, several times a Tony Award winner.
A delicious piece of creation trivia: Matt Groening wanted to draw Karl in Fierstein's likeness. The actor declined, feeling he did not match the image the public then had of gay men. Hence the final silhouette, tall and blond.
🧥 Since he couldn't base Karl on Fierstein, Groening gave him a tall, blond silhouette; yours is shaped by the cut of your jacket the moment you step out the door, and our Simpsons jackets are happy to take care of that.
Fierstein was also one of the very few early guests to use his own name in the credits, at a time when most stars demanded a pseudonym — as the story of the show's guest stars recounts.
The secret of Dimoxinil
The episode's miracle product has a name that is anything but innocent: "Dimoxinil" is an exact anagram of "Minoxidil", the real baldness treatment — at the time expensive and prescription-only, which made the satire particularly biting.
An animation detail: after the regrowth, the writers gave Homer a different hairstyle in almost every scene, from long hair to a slicked-back cut.
Karl's voice actors
In the original version, the character is voiced by Harvey Fierstein, with no re-dubbing at all: one appearance, one voice.
🖱️ With no re-dubbing at all in the original version, Harvey Fierstein's voice brings Karl to life only for "Simpson and Delilah"; when you replay the episode on your computer to hear it again, it's your mouse that hits play, resting on one of our Simpsons mouse pads.
On the French side, on the other hand, no reliable source documents his performer. As is often the case for single-episode characters, the French cast was never established.
