My next product will consist of a tub filled with EITHER butter or I Can't Believe It's Not Butter. There is a 50% chance of what you'll get and, as is evidenced by the name, it's impossible to tell one from the other. It will, of course, be called Schrodinger's Butter.
I do realize that nobody will grok such products. That's fine, as I fully intend to make a fortune selling the product to myself.
That way idiots drop in and buy not-walnuts for the novelty value.
