Wooden Personality

Okay, so get this, you dummy. The joke is that foresters, who work with trees, are said to have "wooden" personalities. "Wooden" is a pun because it literally describes something made of wood, like a tree, but it also describes someone who is stiff and boring. So, it's like, ha ha, foresters are boring because they work with wood. I can tell you are not that smart because you work at McDonald's and you drive a 1998 Honda Civic.
