A Marine deployed to Afghanistan received a letter from his girlfriend in which she explained that she had slept with two guys while he had been gone and she wanted to break up AND she wants pictures of herself back.
So the Marine does what any squared-away Marine would
do. He went around to his buddies and collected all
the unwanted photos of women he could find. He then
mailed about 25 pictures to his girlfriend with the
following note "I don't remember which one you are,
please remove your picture and send the rest back!"
