Three men, Mr. White, Mr. Brown and Mr. Green, were in the habit of meeting in a local doughnut shop every morning for coffee and doughnuts.
One morning as they were sitting at their usual table, Mr. White remarked, "Hey, will you look at that. We're each wearing a colored baseball cap today." One white cap, one brown cap, and one green cap. But interestingly, no one was wearing a cap of the color that matches his name.
At this, the guy wearing the green cap says, "Oh you stup', that doesn't mean anything, it's just coincidence. Shut up and eat your doughnut."
The question is: What color cap is each man wearing?
