The pranks we play (or think about)

So in my company we're a small group of three system admins. Today we were talking through the logistics of a scenario to archive custom form data in closed objects by uploading the custom form as a PDF on closure through Fusion (goal is to prevent any future data loss through deprecation of fields over time).

Admin A who was putting it into the system wondered out loud if he should automatically generate a proof on these, and Admin B said "hell, no". I said "yes, and make sure that Admin B is set as an approver", which brings me to my question:

Have you ever pranked another admin (or what are some good pranking ideas you've come up with) in Workfront?

PS: we didn't carry through with it, because we have a lot of document uploads, and Admin B took the potential threat with good humor.

HAPPY FRIDAY AND HAVE A GREAT WEEKEND :)
