JEST FOR FUN

From a retired soldier:

I was stationed on Leyte during World War II. Although the region was 
secure, sometimes the enemy tried to infiltrate our food-storage area. 
One such adversary, dressed in GI clothing, once worked himself into 
the noontime chow line. Our camp cook spotted him, reached under the 
serving table for his pistol and yelled for the MPs who were 
patrolling the area. After it was all over, we asked the cook how he 
knew the man was an enemy soldier. "I figured it wasn't one of you 
guys," he said, "'cause he was coming back for seconds."
