The QR Code was invented in 1994.  When you point a smart camera at it, it offers to take you to a URL (a website). This one takes you to a website called wemailcoconuts.com where you can buy this shirt.

If my plan (it just might) works - you'll be stuck in an infinite loop of ordering shirts and going to the website and ordering shirts.

I will rule the world of qr coded tshirts, dominion over all things of real value.

 For $30 plus whatever shipping costs says,  FREE SHIPPING, I'll mail you one. This is a Print on Demand product
