Round 2: The "I'm Not Lying" Edition
As per Mandate 4, we are required to provide workarounds for all your needs. In this case, we've got a workaround for your "I'm not lying" needs.
We've developed a patented, highly-effective "I'm Not Lying" device. It's a wearable wristband that emits a high-pitched whine whenever you're caught fibbing. It's not foolproof, but it's a good start.
