When we first got a microwave back in the late 70's my younger brother (he was about 8 or 9 at the time) decided he wanted to cook an egg in it, but he wanted a hard boiled one so he stuck that puppy in the micro shell and all. He set the timer for about 15 min. (that's about how long it takes to hard boil one)
after about the 5th minute that thing exploded all over the inside the mw oven. About that time mom came home from work and just about had a heart attack seeing the mess in her brand new kitchen appliance. (I just about died laughing)
