I have to chime in here at the risk of making myself look like an idiot.
The most worthless item I ever purchased was a set of "Eggies". They are little egg-shaped containers that you put egg beaters in, and then boil them, to make faux hard-boiled eggs. I was thinking less calories and cholesterol at the time, that's my only defense. The things never worked - they either fell apart in the boiling water, or the egg beaters oozed out the sides. At least I only wasted ten bucks on them.
