A farmer gets sent to jail, and his wife is trying to hold the farm together until her husband can get out. However, she’s not very good at farm work, so she writes a letter to his husband in jail: “Dear sweetheart, I want to plant potatoes. When is the best time to do it?”
The farmer writes back: “Honey, do not go near that field. That’s where all my guns are buried.” But because he is in jail, all of the letters are censored. So when the jail guards and the police read this, they all send in a team to dig up the entire potato field looking for the guns.
After two full days of digging, they did not find any single weapon. The farmers then writes to his wife: “honey, now is the time, you can plant the potatoes”
