As the name implies, the “Wrongulator” is a calculator that gets everything wrong all of the time. Just toss a few of these in your accounting department and watch the mayhem ensue.
It is, quite possibly, the cruelest and most dangerous prank you could ever pull at work. Well, it woud be if they still used regular calculators.
The major issue is that it is unclear how close the phony answers are to the correct ones. Sufficed to say, if every problem I typed in ended in the result 8008 I would know something was up. Being immature, I would also laugh.
