An Italian grandmother got a nasty surprise when she started washing a bag of potatoes Wednesday - clinking her knife against a lemon-sized WWII grenade.
The 74-year-old, who bought the potatoes in a market near Naples, called the police who disposed of it in a controlled explosion.
Bomb experts said the American-made grenade did not have its pin in but could have gone off if the granny had put it in the pot with the rest of the spuds.
The grenade is believed to have been covered with so much dirt that potato pickers bagged it without noticing anything out of the ordinary.
