Today is the black day in my experiences calendar. I have seen the worst code ever. I found all that mess in our corporate intranet. It has been written by one guy who long left the company and noone looks at it nomore. Other programmers avoid it like a plague and prefer to write new code rather than make changes the existing one.
It was that bad that the only good thing about it was that there were no comments. If there were any, they would have probably be cryptic, badly written, incorrect, and adding to the whole confusion.
