Williams really did say this, on stage at the Roxy Theatre in Hollywood in 1978 — but the recorded line runs “You’re only given a little spark of madness and if you lose that, you’re nothin’,” and he followed it with “Don’t ever lose that, ’cause it keeps you alive.” The neat second sentence “You mustn’t lose it” appears in no performance transcript we could find and carries no citation anywhere we looked; it reads as a later compression.
“You're only given a little spark of madness. You mustn't lose it” Robin Williams, "Off the Wall" (HBO On Location; taped at the Roxy Theatre, Hollywood; premiered 27 October 1978). On stage he said: "You're only given a little spark of madness and if you lose that, you're nothin'." The widely quoted "You mustn't lose it" is a later compression with no documented source. — verified at quotle.info

Performance
Robin Williams: “Off the Wall” (HBO On Location)
Taped
The Roxy Theatre, Hollywood, 1978
First aired
27 October 1978, HBO
You got to be crazy. It’s too late to be sane, too late. You got to go full-tilt bozo. ’Cause you’re only given a little spark of madness — if you lose that, you’re nothing. Don’t ever lose that, ’cause it keeps you alive.
Transcribed from the bit by everwas.com ↗, which prints the lines and names no performance, venue, year or source for them — so the “full-tilt bozo” build-up and the “keeps you alive” tag rest on that transcription alone. The 1978 Roxy attribution comes from Wikiquote’s sourced line ↗, which covers only the first clause: “…and if you lose that, you’re nothin’.” Neither wording contains “You mustn’t lose it.”
Wikiquote’s sourced list for Williams ↗ gives the line as “You’re only given a little spark of madness and if you lose that, you’re nothin’,” citing A Night at the Roxy (1978) — a title none of the other records below use for that taping, which is released as Off the Wall / Live at the Roxy. Reading the two as the same 1978 Roxy set is our inference, not Wikiquote’s. The page has no “Misattributed” or “Disputed” section at all.
That 1978 Roxy taping is Williams’s first HBO special. Wikipedia’s HBO On Location episode list ↗ dates the premiere of Robin Williams: “Off the Wall” to 27 October 1978.
The performance this line comes from is a 1978 HBO special, so it is firmly within US copyright — nothing here is public domain. The polished “You mustn’t lose it” wording has no separately identifiable published source of its own, so quote the documented stage line and credit the special.

What actually changed
This is not a fake quote — it is a real Robin Williams line that has been ironed flat. Three different wordings circulate, and the most popular one is the only one nobody can source.

Wording“You mustn’t lose it” paraphrase
No documented performance contains this sentence. The recorded bit continues “…if you lose that, you’re nothing. Don’t ever lose that, ’cause it keeps you alive” — transcription of the bit ↗.
✓He said it — on stage at the Roxy Theatre in 1978, and better. Wikiquote’s sourced entry ↗ records it as “You’re only given a little spark of madness and if you lose that, you’re nothin’.”
Context
Why he said it
The taping was at the Roxy Theatre in Hollywood in 1978 — Williams’s first HBO special, in the year Mork & Mindy went on the air. The spark-of-madness line is not a standalone aphorism there; it is how he lands a riff about refusing to be sensible. The build-up, as transcribed from the bit, is “It’s too late to be sane, too late. You got to go full-tilt bozo.”
That matters, because the internet version reverses the register. Williams said something rough and defensive — lose it and you’re nothing — and the line that travels is a gentle piece of advice. The polished form spread hardest after his death on 11 August 2014; The Irish Times ran it the next morning ↗, in a third wording again.
You’re only given a little spark of madness and if you lose that, you’re nothin’.
Why the paraphrase is so hard to dislodge
The short form is not a fabrication in the usual sense — nobody invented a sentiment Williams never held. It is a compression: two clauses of stage patter squeezed into a symmetrical couplet that fits a graphic, a tattoo or a caption. That is exactly the shape that survives copying, and exactly the shape that loses its citation on the way.
There is no fact-check to point at either. A search of Quote Investigator returns nothing ↗ for this phrase, so the only documentary anchor is Wikiquote’s sourced entry pointing back at the 1978 Roxy set.

Robin Williams was born in Chicago on 21 July 1951 and started doing stand-up in the San Francisco Bay Area in 1976, working his way up from tending bar at the Holy City Zoo. By 1978 he was the alien Mork — first in an episode of Happy Days, then in Mork & Mindy, which ran to 1982 and made him a household name almost overnight. He died on 11 August 2014, and Wikipedia’s summary of him is the one most people would give: a performer remembered above all for improvisation and for the crowd of characters he could conjure on the spot.
