Have you ever seen the Cup Noodles in the grocery store? They are microwavable noodles, but if you aren't paying attention, the label looks like it says Cup Needles. But, by now people recognize the container and buy it anyway.
So, my plan is to make a product called Cup Needles, make a label that looks similar, and sell it in the same store right next to it. Then, people will buy mine by accident and when they get home they will be confused since they will have a cup full of needles instead of noodles. But by then, it will be too late! So long, suckers! I'll laugh all the way to the bank.
Oh, and I would sell them at a store that doesn't have a return policy.
