Two very old war veterans were walking down a sidewalk toward each other, both of them dragging their right foot along the ground. Neither of them was moving out of the way for the other, but they kept walking straight toward each other. Eventually they were right in front of each other, nose to nose!
One of the men says, “Shrapnel, 1942.”
The other man, not moving, says, “Dog crap, two minutes ago.”
