During the war, a soldier faithfully wrote his mother every week, so she would know he was all right, until one week she didn't get a letter and immediately began to worry. Within a couple of weeks, she got a letter from the Army saying that her son had been captured and was being held in a Prisoner-of-War camp, and they assured her that they had no reason to believe the American prisoners were being mistreated in any way.
A few weeks later the woman finally received another letter from her son, it read: "Dear Mom, Try not to worry about me, they are treating us well and I'll be released as soon as the war is over. Make sure that little Teddy gets the stamp for his collection. Love you, Joe" The woman was overjoyed to hear the news, but was confused because she had no idea who "little Teddy" was. She decided to steam the stamp from the envelope and have a look.
When she did she saw that written on the back of the stamp were the words:
"They've cut off my legs."
