Here's a QR code in ad withe the line "Sharpen up" that displays anything but sharp thinking.

Someone forgot to think about this, didn't they?

They're displaying the QR code in an ad, on a device that can photograph and scan QR codes... provided they QR code is not displayed on the actual device...

Yeah. Thanks Ashadi Hopper a.k.a @ashadihopper for spotting it and letting us use the photo.
