ok, this one cracked me up too (I didn't make any of these, but I thought they were good)
if(computer.fail==true){
background.setColor(blue);
user.frown();
sys.shutdown();
user.scream("OH, FUCK YOU");}
edit: and this one too
There once was a man named Bertold
Who drank beer when the weather grew cold
As he reached for his cup...
"NEEEEVER GONNA GIVE YOU UP!!!"
Oh, snap! You just got limerickrolled!
edit: another for fun
A programmer started to cuss
Because getting to sleep was a fuss
As he lay there in bed
Looping 'round in his head
was: while(!asleep()) sheep++;
and another
Among all these poems, a few
of the best recite old jokes anew.
But there's one I don't see,
And the reason must be:
In Russia, the limerick writes you.
