The Egg Peeler.....
My Grandma was a nut for mail order things. She ordered some of the craziest things off infomercials. Well they came our with a hard boiled egg peeler and Grandma in her infinite wisdom sent an order in-not for one mind you but like 4-she always figured one of us kids could use these nifty gadgets too, that went for everything she ordered or got thru the mail :) Well she got this cool little gadget home and had to try it out of course. So she sets it up on her table with her hard boiled eggs, good to go and set for action. So she proceeds to get the egg all in her little gadget and gets soing and things are going smoothly until that is, the egg flies all the way across her house into the porch onto her floor. Welll needless to say that was the end of her egg peeler usage LOL she gave away the egg peelers to her kids/grandkids in the hopes that they had better luck than her.
