Funny Source Code Comments

I recently stumbled upon an awesome Stack Overflow thread, entitled “What is the best comment in source code you have ever encountered?”.

As you might have guessed, it is a collection of funny source code comments, provided by developers all over the world. Take a look at it, it could definitely make your day.

I am reposting here my personal favorites from that long long collection:

// sometimes I believe compiler ignores all my comments

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

// 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.

// drunk, fix later

// Magic. Do not touch.

return 1; # returns 1

double penetration; // ouch

/////////////////////////////////////// this is a well commented line

// I am not sure if we need this, but too scared to delete.

// I am not responsible of this code.
// They made me write it, against my will.

//Dear future me. Please forgive me.
//I can’t even begin to express how sorry I am.

options.BatchSize = 300; //Madness? THIS IS SPARTA!

// I have to find a better job

// hack for ie browser (assuming that ie is a browser)

} catch (PartInitException pie) {
// Mmm… pie

// John! If you’ll svn remove this once more,
// I’ll shut you, for God’s sake!
// That piece of code is not “something strange”!

try {

catch (SQLException ex) {
// Basically, without saying too much, you’re screwed. Royally and totally.
catch(Exception ex)
//If you thought you were screwed before, boy have I news for you!!!

// Catching exceptions is for communists

// If you’re reading this, that means you have been put in charge of my previous project.
// I am so, so sorry for you. God speed.

// if i ever see this again i’m going to start bringing guns to work

// The magnitude of this hack compares favorably with that of the national debt.


// If this code works, it was written by Paul. If not, I don’t know who wrote it

//You are not expected to understand this

* If you don’t understand this code, you should be flipping burgers instead.


//Abandon all hope yea who enter beyond this point

//Mr. Compiler, please do not read this.

catch (Ex as Exception)
// oh crap, we should do something.

// TODO make this work

// If you delete the credits, I will fucking kill you.

// This is crap code but it’s 3 a.m. and I need to get this working.

// For the sins I am about to commit, may James Gosling forgive me

// Houston, we have a problem

// If I from the future read this I’ll back in time and kill myself.

Pure awesomeness… Don’t forget to share your own favorites in the comments!

  1. Nice post!! had a good time reading this. thanks for sharing….

  2. Krishna says:

    I’m never laughed over a computer related stuff like i did a minute by reading all the source code comments… Just too good!!!

  3. Luke says:

    Just came across this double comment while going through some painfully horrendous legacy code:

    ‘ We have events, so things get good here! <- what do you mean things get "good" here? Nothing is remotely good in this page ever!

  4. Young says:

    That’s funny.HAHA

  5. Stuart says:

    /*We don’t care about performance, only accuracy because
    * we know IT can just throw a few more servers up up their asses.
    * We also don’t care if you can’t comprehend this, because you are
    * probably an offshore developer with poor English. */

    • Alex says:

      Hey Stuart,

      I assume that’s a SQL Code comment block, right? I dislike SQL programmers that don’t optimize their code, they are just bad programmers… I wanted to get that off my chest.

  6. Robert says:

    A friend of mine worked in the Houston office of Amoco (a large oil company), which later merged with PB. The following comments appeared next to an unknown error code…

    // Shut her down, Clancy. She’s pumping mud.

  7. Neil Modi says:

    \\ Awesomest post ever i Read
    \\ i have read this all lots time but never thought such type of blog post
    \\ incredibly collected.

  8. David says:

    One I recently came across:

    // Initiate the matrix – not quite as sinister as it sounds

  9. bomco3 says:

    Toto, I’ve a feeling we’re not in Kansas any more

  10. Arun prasad says:

    ################Good One############ Few More below…!

    // If this comment is removed the program will blow up

    try {

    } finally { // should never happen


    Catch (Exception e) {
    //who cares?

  11. Nicki says:

    – There is a bug here that I did not have the time to fix right now

  12. Dev says:

    LOLz :) … This reminds me of similar funny comments we used to add in the log files.

  13. Ranjith says:

    I use to put these…
    //Enter the new Dragon !!

  14. maelorin says:


    #Fix what follows, I beg of you…

    //This does nothing useful, but the rest of this code fails to compile without it
    //Don’t bother wasting time figuring out why.

    * What is this code supposed to even do?

    ## AND, LO, YOU DID

    // insert comment here
    function f(x,e);
    printf “insert function to do stuff here”;

    ** Boss man be mad when he read this code

    ** Only joking. Boss man never read code

  15. Mik says:

    Haha, i had to put a few aside :D you never know when you’ll need to use them.
    Also, here are a few more :

    #define TRUE FALSE //Happy debugging suckers

    and a favorite of mine :

    // 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

  16. This reminds me: One time when I was trying to locate a source of performance issues, I finally found the right method, which contained:

    // TODO Can cause performance problems, fix in the future

  17. DarC says:

    my favourites

    // – FFS what now it was working till you touched it

    popped up in many a log file for some reason

    // – leave me alone I might not be the prettiest but at least I work (unlike some)

  18. David P says:

    In the late 70′s I was told a story by a Control Data mainframe software engineer, I’m not sure it’s true, but it goes like this:

    One night two operating system engineers were sitting working on a set up updates to the next OS release. The junior of the two finds himself in a branch of code but is unsure what to do if it ever got executed. So he floats over to the senior guy and explains the situation. After thinking for a bit the senior guy says “That will never happen because…” and reels off a set of reasons demonstrating that he clearly understands WAY more than the junior guy. Mollified, but still unsure, the junior guy goes back to work.

    Within a month of the release going live, a mainframe experiences a critical stop. The message on the operator’s console read:

    “This can’t have happened, but it did, so tell Fred he owes me $50″
