Basically a potato gun is a pipe bomb cannon.
Now… When I saw this I was afraid to ask my Mom if one of the injured (Coffey) was the from the same family as my intelligent, well behaved, and bit puritan first cousin (who has always lived very close to Cable, Ohio) was married into.
Indeed, I was sadly right when Mom wrote me about the story with the confirmation. One of the men injured is my cousin’s husband’s cousin. (What does that make me?).
The story certainly got around more than just Ohio, it made it all the way to the pinnacle of stupid internet news – Fark.
