Guns Buried in the Garden

An old man lived alone in Northern Ireland. His only son was in  prison. The old man wanted to plant some potatoes in his garden but he didn't know anyone who would help him plow up the garden.  
 He wrote to his son about it, and received this reply, "For HEAVENS SAKE, don't dig up that garden, that's where I buried the GUNS!"
At 4 AM the next morning, a dozen British soldiers showed up and dug up the entire garden, but didn't find any guns.
Confused, the man wrote to his son telling him what happened and asking him what to do next.
His son's reply was: "Just plant your potatoes."

埋在花园里的枪
    一个老人独居在北爱尔兰，他的独生子正在坐牢。老人想在花园里种些土豆，但不知道谁可以帮忙把泥土翻松。他写信想儿子提及此事，儿子回信说道：“看在上帝的面上，千万不要翻松花园的泥土，我把枪埋在那儿了。”
    第二天凌晨4点，一队英国士兵出现在老人家中，在花园把土地翻遍，但并没有找到任何枪支。”
    老人写信告诉儿子这件奇怪的事情，问到底发生了什么事情，下一步应该怎么做。
    儿子回信道：“你只管种土豆好了。”
