Spoons points us to this story.
Ukrainian police have arrested a man caught with a gun and a cabbage he intended to use as a silencer.
I vaguely remember reading about The Jackal years ago and that he used a potato as a silencer in his early, and less profitable, days.
If you do it right, it’s actually possible to turn a 2-liter coke bottle into a silencer (but for only one shot).
