Here is an idea from my notebook. Nothing earthshattering. A t-shirt with a small breast pocket for holding your PEZ dispenser.
Back in the day, when PEZ MP3 was a blog, I half-jokingly floated the idea of a Yankees logo Urinal Cake that could be sold to Boston bar owners and vice-versa. Turns out the custom urinal cake business is real. Complete with clever domain names and spokesmodels.
I have had big ideas all my life. Normally, I think about them, a lot. But I don’t follow through. One time I did. It ended up being the PEZ MP3 player.
