An old farmer wrote to his son in prison."This year I won't be able to plant potatoes because I can't dig the ground, I know if you were here u would help me".The son wrote:"Dad don't think of digging the ground because that's where I buried the guns".Police reads the letter and the very next day, the whole ground was dug by police looking for guns, but nothing was found...Next day the son wrote again"Now plant your potatoes dad, it's the best I could do from here".
