Is it a commercial? Is it propaganda? Or is it, as I suspect, pure poetry? This Trader Joe's fan wrote a commercial, complete with off-key singing and awesome lyrics. Who among us, for example, hasn't had our heart's cockles warmed by the thought of how reassuring it is that those lime and chili cashews, balls of ice cream covered in flour and tiny free cups of coffee will (probably) be at TJ's every time we go? And that instead of what's on our list of essentials, we'll end up buying odd little snacks. . .
