THen there was the guy who inserted a listing into a high-tech parts catalogue for a new memory chip, which was listed as a "write-only memory chip". It gave some spurious technical numbers as specs, so it looked like a real chip listing.

The guy actually got some serious enquiries about the fictitious item from procurement people.

Ya gotta wonder if these guys read what they're reading!

(Pause and reflect on the possible uses of write-only memory, if this seems obscure to you).
