Re: Been there, done that, tipped the swear jar
In a previous life I was a Foxpro programmer. Ca 2.6. We did a lot of small custom databases and associated data entry screens with reports. We knew our clients well and often managed their micro LANs and computing needs at the time.
Co-owner of the company used to put Easter Eggs in the code that would only appear very briefly when certain users were logged in. For example, in 1 in 100 or so +random offset, error messages would appear very briefly, "You've done it again big nose" and "Well, that was smart you waste of space". Then 2 or three seconds later, the regular error message would appear. No offensive language per se, but enough to make one say, What?
Messages and variability changed with each upgrade too.
