Comment Bill the Galactic Hero. (Score 1) 290
A multispectral data processing program I wrote back in my college days: Part of launching it was giving it the date the data was collected. This was sanity checked against the system clock. Dates like before the construction of the scanners we usually used had a reasonable error message, asking if you were sure and giving a chance to reenter.
The message for a data collection date later than the data processing date was: "WONKITY! [name of institute] processes TOMORROW'S data TODAY!"
This was a reference to an incident in a humorous science fiction novel: _Bill the Galactic Hero_. The protagonists are sneaking around and are discovered by a cleaning robot and challenged as security breaching interlopers. One of them "bashes the robot on the braincase with a spanner", causing it to say "WONKITY!" and stagger away, rather than reporting them to security.

When I was working on a typesetting system for newspaper publication, I heroically refrained from having it very occasionally insert "fnord" into the text. (See _The Illuminatus Trilogy_ for the joke, which is FAR to complex to explain here.)
