‘Unexploded Grenade’ Found in German Forest Actually Just a Butt Plug An object thought to be an unexploded World War II-era hand grenade found in woodland in Germany was actually a rubber sex toy, police have said. Earlier this week a jogger discovered what she thought was a grenade in the Bavarian forest near the city of Passau in the south of Germany, and called police. A police bomb squad were called to the forest in Hauzenberg, but they quickly deemed the item to be non-threatening. The bag the grenade was in also contained lubricant, two unopened condoms, and a USB cable – objects which helped bomb disposal experts to reach their conclusion.
