Ali genuinely used this boast — reporters recorded versions of it in the Village Voice on 25 July 1974 and The New York Times on 29 June 1975, and it survives on film in When We Were Kings. But he did not invent it: Quote Investigator traces the light-switch gag to April 1917 ↗, twenty-five years before Ali was born, and no documented Ali source matches the smooth wording that circulates online.
“I'm so fast that last night I turned off the light switch in my hotel room and was in bed before the room was dark” Muhammad Ali did use this boast, but he did not invent it. The light-switch gag was in print by April 1917 and Satchel Paige told it about Cool Papa Bell before Ali did. The versions actually documented from Ali — Village Voice, 25 July 1974 ("I'm so fast last night I cut the light and hit the switch and was in bed before the room was dark") and The New York Times, 29 June 1975 — do not match the polished sentence that circulates online, which has no known source. Chronology: Quote Investigator, "Quote Origin: When He Turned Out the Light He Was in Bed Before the Room Was Dark," 12 June 2013.

The popular wording
No documented source
I’m so fast last night I cut the light and hit the switch and was in bed before the room was dark.
Ali, as reported from his training camp
That is the wording the Village Voice printed on 25 July 1974, as quoted and cited by Quote Investigator ↗. Eleven months later The New York Times reported it differently again: “I’m so fast I hit the light switch in my room and jump into bed before my room goes dark.” Neither is the sentence that circulates today.
April 1917 — a correspondent in The Marines Magazine writes of a Marine at Fort Mifflin that “he can switch off the lights and be back in bed before the room gets dark,” the earliest instance Quote Investigator locates ↗. Ali would not be born for another twenty-five years.
1919 to 1945 — the gag passes through vaudeville and radio: the Chicago Tribune on the comedy team Moran and Mack in 1919, a Paul Bunyan children’s book in 1937, an Abbott and Costello radio script in 1945, all documented with citations by QI ↗.
1969 and 1971 — Satchel Paige tells it about Cool Papa Bell in the Washington Post and in Jet. Wikipedia ↗ records the faulty-wiring hotel story behind it — and that Paige told it with the explanation left out.
1974 to 1996 — Ali uses it in his Zaire training camp, reported by the Village Voice on 25 July 1974, and again to The New York Times on 29 June 1975. Archival footage of him telling it appears in the 1996 documentary When We Were Kings ↗ — where he says “my bedroom.”
The exact sentence that circulates online has no identified source, so no rights status can honestly be asserted for it. The wordings that are documented sit inside copyrighted twentieth-century journalism — the Village Voice of 25 July 1974 and The New York Times of 29 June 1975 — both well after the 1931 public-domain cutoff, so treat any quotation of them as in-copyright and attribute it. The 1917 Marines Magazine item is old enough to be public domain, but it is a different sentence about a different man.

Fact-check
What’s actually wrong here
This is not a fabricated quote — Ali really did tell this joke, on the record and on camera. Four things about the popular version are still wrong.
✕
The joke itselfNot Ali’s invention in print by 1917
Quote Investigator ↗ locates the boast in The Marines Magazine of April 1917, about a Marine at Fort Mifflin, and in the Chicago Tribune in 1919 in the act of the comedy team Moran and Mack. QI’s conclusion is that the gag “has been adopted by a variety of comedians and athletes over the decades.”
✕
The wordingNo documented Ali source says this paraphrase
The two contemporaneous reports QI cites ↗ read “I cut the light and hit the switch and was in bed before the room was dark” (Village Voice, 25 July 1974) and “I hit the light switch in my room and jump into bed before my room goes dark” (The New York Times, 29 June 1975). The film transcript of When We Were Kings ↗ has “my bedroom,” not “my hotel room.” No aggregator circulating the polished sentence — Quotefancy ↗ among them — cites a date, a venue or a source for it.
✕
The book credit“Tales from the Land of the Sufis” database error
Goodreads ↗ credits the line to “Mohammad Ali” and sources it to Tales from the Land of the Sufis by Mojdeh Bayat — a book on Sufi mysticism with no connection to the boxer. Goodreads itself notes that its quotes are community-submitted and unverified.
✕
The earlier claimantSatchel Paige, on Cool Papa Bell
Paige was telling this about the Negro Leagues outfielder James “Cool Papa” Bell years before Ali — in the Washington Post in 1969 and in Jet in 1971 ↗. Wikipedia ↗ adds that the story had a real hotel-room origin: faulty wiring delayed the lights, and Paige told it with that detail removed. Paige did not originate the gag either.
✓Ali told this joke and told it well — but it was already more than half a century old when he got to it, and the sentence pinned to his name online is not one any source records him saying ↗.
Context
Why this one stuck to Ali
Ali’s public persona ran on exactly this kind of comic hyperbole, so a boast about impossible speed sounds more like him than like anyone else who ever told it. That is the whole mechanism of quote drift: a line migrates to whoever it sounds most like. By the time Ali used it in 1974, the joke had already been told about a Marine at Fort Mifflin, by a vaudeville double act, by Abbott and Costello, and by Satchel Paige about the Negro Leagues outfielder Cool Papa Bell.
What makes Ali’s version worth taking seriously anyway is that he really did tell it, on the record, and it survives in archival footage from his Zaire training camp. The problem is not that he never said it. The problem is that the internet credits him with inventing it, in words he is not recorded as using.
A boast this good does not stay with the man who made it up. It goes to the man it sounds like.
The chain of tellers, as Quote Investigator documents it
Quote Investigator’s chronology ↗ runs: The Marines Magazine, April 1917 — the Chicago Tribune on the comedy team Moran and Mack, 1919 — the Hutchinson News, 1920 — a Paul Bunyan children’s book, 1937 — an Abbott and Costello radio script, 1945 — the Washington Post on Satchel Paige and Cool Papa Bell, 1969 — Jet, 1971 — then Ali in 1974 and 1975.
The Satchel Paige version has a backstory Ali’s does not. Wikipedia’s article on Cool Papa Bell ↗ recounts that faulty wiring in a hotel room left a short delay between the switch and the lights going out, long enough for Bell to get into bed — and that Paige liked to tell the story with the explanation left out.

1942–2016 · American boxer, three-time world heavyweight champion
Born Cassius Marcellus Clay Jr. in Louisville in 1942, Ali boxed professionally across three decades (1960–1981) and held the world heavyweight title three times between 1964 and 1979, becoming one of the most recognised figures on earth. He was as famous for his talking as his fighting — Wikipedia describes his trash talking, often free-styled with rhyme schemes and spoken word poetry, a style he took partly from the wrestler “Gorgeous George” Wagner. That reputation is exactly why decades of anonymous boasts, this one included, drifted onto his name.
