I knew a guy named Steve who ensured job security using Delphi. He wrote this malevolent and semi-sentient framework called The Framework, that managed to combine the ugliness of COBOL with the programmer-friendliness of... well, COBOL, now I think of it. Delphi has a couple of different flavours of inheritence built in -- object inheritence, controls owning subcontrols, TFrames embedded in TForms -- but The Framework increased that number somewhat. From memory, I think I counted nine different kinds of hierarchy, all intermingling in weird and utterly undocumented ways.

For all I know, he's probably still working there. The poor, poor bastard.
