You can't polish a turd
I have an application that I maintain. I was brought into my current project to make said application 'stable.' It was written by a moron and designed by a cobol programmer who didn't know the limitations of a web applications. Promises were made and it was a steaming pile of crap.
Anyone asks me about said application??
"What can I say... you can't polish a turd."
Try and use it in the office sometime today. Very rarely will the opportunity arise to use it, but its usually well worth it
