I'm not even lying...that actually happened to me!!!!
I was only quite young, and i boiled a couple of eggs...i opened one, and it wasn't done-so i put the other in the microwave...when i got it out, i popped it in the egg cup. Then, as you do, I tapped it with the spoon. Just as the spoon touched the egg-the fucker exploded all over the kitchen and my face...it hurt-but i didnt go to hospital...it hurt-but i was laughing too hard to care.(can't remember if it was sonya or hannah who was there at the time)
The kitchen was covered with egg remains.
