Another one from Thomas M.

A mother was pleased with the card her son had made her for Christmas, but was puzzled as to the scraggly-looking tree from which many presents dangled, and at the very top, something that looked strangely like a bullet. She asked him if he would explain the drawing and why the tree itself was so bare, instead of a fat pine tree. “It’s not a traditional Christmas tree,” he explained.

“It’s a cartridge in a bare tree.”
