From the creator of xckd comes a database similar to bash.org:

LimerickDB.

Check it out, there are some pretty good ones.

if(computer.fail==true){
background.setColor(blue);
user.frown();
sys.shutdown();
user.scream("OH, FUCK YOU");}

i like that one for being completely different

From what? There are quite a few code limericks out there.

Different from what normal human beings are used to seeing, you ferrous cranus bastard?

I've only read a few, but I love the one cut in half to look like haiku, and I really cracked up at this one:

"There once was a small juicy orange...
...fuck."

That would be about how much I'd be able to write.

I'll try to avoid offending the resident cannibalistic neo-luddites next time.

There once was a man from Miyong
Who's last name it was pronounced Long
But the girls all report,
Infact it was short,
Regarding the length of his Wong.
