# "Honi soit qui mal y pense"

In the Apollo 11 LEM source code, in the Burn Baby Burn master ignition routine, one of the most emphasized comment is a French citation, HONI SOIT QUI MAL Y PENSE.

According to wikipedia, this locution is

is a maxim in the Anglo-Norman language, a dialect of Old Norman French spoken by the medieval ruling class in England, meaning "shamed be whoever thinks ill of it" […]

Note that the same Wikipedia article acknowledge the presence of that locution in the Apollo source code, but only provides sources, not explanations.

(also, the same locution with two n to Honni, also valid in French, is the French title of an American movie)

Why was such a locution placed there? Is their any evidence of why that comment was written and placed there?

• Margaret Hamilton might know it.

• I have no references, but I would imagine that this comment (along with the one that follows, "NOLI SE TANGERE" -- "don't touch this") is a message to the rest of the team implying something like "don't criticize or change this code, it was extremely difficult to create"... Feb 1 at 18:13

• There seems a typo, it should read NOLI ME TANGERE

• More of an aside than an answer: Comments such as those would be viewed as highly unprofessional nowadays. Sea slugs (aka bottom dwelling lawyers) have trained organizations to train their programmers not to write cutesy comments. Said sea slugs pore over current and old versions of the code, commit messages, etc. Cutesy code, code comments, commit messages, etc. have resulted in the sued organization ending up losing the lawsuit.
