Aaaah don't talk about enterprise software. That's my father's entire career- working with that nonsense. Worse yet, he's the implementation consultant- he has to explain how it works, from the perspective of a user, to other people who know nothing of how any of it works and why it can't do certain things. I've seen brick walls less dense than these idiot's heads, both for getting them to understand and smashing your head against when they don't.
The best I've seen was a parody of the tendency of GNU programmers to include way too many features in their software. As a result the programmer implemented coloured output and all sorts of other useless things.
I've seen other "enterprise" fizz buzz implementations in Java too, but this one takes the cake. The next thing to add should be the ability to receive the results by e-mail (one at a time, preferably).
The best one I've done: http://ideone.com/uZYBWM (hint: run it with "qemu-system-i386 -fda <filename> -boot a").
