Software can and should be fun, especially if it's harmless. Where is the hacker spirit?
We should stride to make software a little more fun, have a little more character and have certain human touch to it.
Obviously don't have your database write "FART" in place of data, just because the user is "dave" and it's not 16:45 in the afternoon, but harmless messages in the code, weird log messages and otherwise harmless reactions to predetermined inputs.
if you invoke man after midnight it should print "gimme gimme gimme", because of the Abba song called "Gimme gimme gimme a man after midnight"
You might not agree that that's a good requirement. Others' requirements aren't always aligned with yours :)
Requirement fulfilled, under budget too :))
And shall be _tested_ _before_ delivery.
I know, it's expensive ... /s
