Meet the Wrongulator – The Calculator that always gives the wrong answer! Lend it to your friends and watch as the Wrongulator always gives them the wrong answer.

Got some beef with some folks over at the Finance department? Have a grudge against a co-worker who just won’t stop filching your pens and markers from your table when you’re not looking? Then it’s time for some pranking and sweet revenge with the Wrongulator.

This is a calculator with an erroneous twist. Expect it to churn out incorrect answers and perform bogus calculations with the user being none the wiser and watch in the background as your begrudged enemies stare at their reports and spreadsheets in frustration. Don’t go to far with the prank though, because we don’t want anyone to lose their jobs now. But that’ll teach people at the office a lesson when it comes to messing with you.

Just be prepared for their retaliation.
