What single line of code would you put on a programming shirt?

If it has to be one line, the comment:

    You are not expected to understand this.

from https://en.m.wikipedia.org/wiki/A_Commentary_on_the_UNIX_Ope... .

:(){ :|:& };:

Though, now that I think about it, I'm pretty sure I've already seen that as a t-shirt.

// DON'T TRY TO FIX THIS, IF REMOVED BREAKS PRODUCTION

If the footwear was appropriate, you could say something like:

>BOOT DEVICE NOT FOUND;

>FALLING BACK TO SNEAKERNET . . .

Bash fork bomb. In fact, I have the tshirt.

Good explanation here: https://www.cyberciti.biz/faq/understanding-bash-fork-bomb/

The export-restricted perl munition t-shirt text:

#!/bin/perl -sp0777ilMLa^lN%0]dsXx++lMlN/dsM0

// TODO: Fix me

Haven't seen this in a while;

Fast inverse square root

    import pdb; pdb.set_trace()

Or as one of these 'modern' 'linters' like to 'fix' it to:

    import pdb
    
    
    pdb.set_trace()

I’d put $year: ERR_REQUIRE_ESM require of ES module strip-ansi not supported, cause people should know that it’s 202x and we are still practically almost already there.

    const char* pszTimestamp = "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks";

I have a shirt from WWDC 2014 that I find humorous:

func yTown() { print("San Francisco WWDC 2014") }

body { display: none !important; }

I'm not sure exactly, but I'd probably write it in Whitespace.

20 GOTO 10

System.out.println("Hello World");

const y = f => (x => f(x(x))) (x => f((...y) => x(x)(...y)))

for (;;) { printf("%s\n", "I'm in danger!"); };
