Qual é o melhor comentário no código fonte que você já encontrou?

Sou particularmente culpado disso, incorporando comentários não construtivos, poesia de código e pequenas piadas na maioria dos meus projetos (embora eu normalmente tenha senso suficiente para remover qualquer coisa diretamente ofensiva antes de liberar o código). Aqui está um que eu particularmente gosto, colocado muito, muito abaixo de um 'Objeto de Deus' mal projetado:

/**
* For the brave souls who get this far: You are the chosen ones,
* the valiant knights of programming who toil away, without rest,
* fixing our most awful code. To you, true saviors, kings of men,
* I say this: never gonna give you up, never gonna let you down,
* never gonna run around and desert you. Never gonna make you cry,
* never gonna say goodbye. Never gonna tell a lie and hurt you.
*/

EU SINTO MUITO!!!! Eu simplesmente não pude evitar .....!

E outra, que eu admito que ainda não me libertei, apesar de estar muito tentada a fazê-lo em uma das minhas aulas menos intuitivas:

// 
// Dear maintainer:
// 
// Once you are done trying to 'optimize' this routine,
// and have realized what a terrible mistake that was,
// please increment the following counter as a warning
// to the next guy:
// 
// total_hours_wasted_here = 42
// 

Exception up = new Exception("Something is really wrong.");
throw up;  //ha ha

//When I wrote this, only God and I understood what I was doing
//Now, God only knows

stop(); // Hammertime!

Isso parece impedir que idiotas mexam no meu código ...

// Autogenerated, do not edit. All changes will be undone.

// sometimes I believe compiler ignores all my comments

// I dedicate all this code, all my work, to my wife, Darlene, who will 
// have to support me and our three children and the dog once it gets 
// released into the public.

//Code sanitized to protect the foolish.

Atualização: o autor original do código se apresentou, portanto, devo dar crédito onde é devido. Dan McKinley deixou a empresa com a qual eu estava logo depois de começar, e ele fala mais sobre o código, explicando alguns antecedentes e mais alguns "WTF's" que 'Richard' escreveu.

// somedev2 -  5/22/07 Temporary my ass

// drunk, fix later

Queria estar brincando. E conhecendo o desenvolvedor que escreveu o código, acho que ele quis dizer isso literalmente.

// Magic. Do not touch.

#define TRUE FALSE //Happy debugging suckers

// I'm sorry.

return 1; # returns 1

/* This is O(scary), but seems quick enough in practice. */ 

seguido de quatro for-loops aninhados

// Replaces with spaces the braces in cases where braces in places cause stasis 
   $str = str_replace(array("\{","\}")," ",$str);

// At this point, I'd like to take a moment to speak to you about the Adobe PSD
// format. PSD is not a good format. PSD is not even a bad format. Calling it
// such would be an insult to other bad formats, such as PCX or JPEG. No, PSD
// is an abysmal format. Having worked on this code for several weeks now, my
// hate for PSD has grown to a raging fire that burns with the fierce passion
// of a million suns.
//
// If there are two different ways of doing something, PSD will do both, in
// different places. It will then make up three more ways no sane human would
// think of, and do those too. PSD makes inconsistency an art form. Why, for
// instance, did it suddenly decide that *these* particular chunks should be
// aligned to four bytes, and that this alignement should *not* be included in
// the size? Other chunks in other places are either unaligned, or aligned with
// the alignment included in the size. Here, though, it is not included. Either
// one of these three behaviours would be fine. A sane format would pick one.
// PSD, of course, uses all three, and more.
//
// Trying to get data out of a PSD file is like trying to find something in the
// attic of your eccentric old uncle who died in a freak freshwater shark
// attack on his 58th birthday. That last detail may not be important for the
// purposes of the simile, but at this point I am spending a lot of time
// imagining amusing fates for the people responsible for this Rube Goldberg of
// a file format.
//
// Earlier, I tried to get a hold of the latest specs for the PSD file format.
// To do this, I had to apply to them for permission to apply to them to have
// them consider sending me this sacred tome. This would have involved faxing
// them a copy of some document or other, probably signed in blood. I can only
// imagine that they make this process so difficult because they are intensely
// ashamed of having created this abomination. I was naturally not gullible
// enough to go through with this procedure, but if I had done so, I would have
// printed out every single page of the spec, and set them all on fire. Were it
// within my power, I would gather every single copy of those specs, and launch
// them on a spaceship directly into the sun.
//
// PSD is not my favourite file format.
