Twenty Years Late But Still Clever: Wrongulator Calculator Only Gives Wrong Answers
The Wrongulator is a cheap $7 solar calculator that's been programmed with bad logic to only give wrong answers. I'm not sure how close the bad answers are to the correct ones, but hopefully close enough so that the error isn't obvious. That, or just 80085 every time. What? They're never not the answer! "What's the hottest part of an overweight man?" Okaaaaaaaay, I stand corrected. (It's the foopa, right?)

Thanks to FSK, who would look great monogrammed on a bathrobe.
