I was doing an asset management project for the CTO of a small company in ASP.NET and the CTO decided to stick his crap smeared fingers into the development because he 'developed' a completely different AS/400 system which everyone complained was like having a dog smear it's balls all over your screen while taking a dump on your keyboard. Fucking idiot would have given me 2 weeks extra work with all the shit he broke if it wasn't for version control.
