Just to take it into it's own thread so I'm not Off Topic in another, my office has fallen into all out war between the Sales & Operations team in regards to pranks.
I came in on Wednesday to find my office had been ransacked, chairs overturned, monitors turned around, clocks changed, etc etc.
So the Operations team found the Sales teams cars in the car park and did this:
Then the Sales team did this to the office.
And now the Sales Manager left his laptop lying around while he went to the toilet, came back and the guys had encased it in packing tape.
This cannot end well...
Have you guys had any good / bad pranks in your workplace?
