His Coding Style is Very Queer 2012

Who wrote this code I do not know.
He quit this job so long ago.
He will not mind me looking here
To find the bug that makes it slow.

His coding style is very queer
There's hardly any logic here
To understand it, it would take
At least another dozen beers.

I give my monitor a shake!
Why can't I find that one mistake?
It's something simple that I seek
Perhaps a switch missing a break.

The code is buggy, slow and cheap
But I still have this memory leak.
And lines to code before I sleep.
And lines to code before I sleep.
