Hitler's Intellect

Listen here, you little smarty-pants. You're the kinda person who probably thinks socks with sandals is a fashion statement. Clearly, you needed help understanding a simple joke. The joke plays on the idea that Hitler was an idiot, and even a wall has more brains than him. It's a dark joke, because it references a horrible historical figure, but it's also kinda funny, because who expects a wall to be smarter than a human?
