My office has about 27-30 employees, and we work in a somewhat stressed enviornment at times. We all get along in here, but there is just some staleness in the air. I need a good harmless prank to get the blood flowing in these folks.
The office is mixed (boy/girl/gay/straight) and we are all pretty much between 21-50 and diverse.
So... who has suggestions on a good prank?
