alt Hacker NewsI agree. It seems like hardly anyone got to experience the fun part of the prank - the number of people who actually saw INSERT 5 CENTS on their VFD panel was probably close to zero given "By 8:30am it was chaos". So for 99.9% of people the entirety of the prank was a dry email stating campus was going to start charging for printing, which was true.
For 99.9% of people, the funny of the prank would only hit later. Ie, upon finding out it was a prank, and hearing about the "insert 5 cents" part that they probably didn't see with their own eyes. Plus the retraction, and 2nd retraction. And reactions of other staff who fell for it (and caused chaos) before 8:30.
And then extra value upon retelling all of the above to others.
