Scrooge's nephew and his guests play the game they called Yes and No toward the end of their Christmas Day gathering, as observed by Scrooge and the Ghost of Christmas Present. The game is very similar to what we might call the game of 21 or Questions.
One person thinks of an object or idea. Other players attempt to identify what has been thought of by asking questions, but the only answers which may be given are "yes" or "no." This forces the formation of questions that can be answered appropriately with one of those two words, giving rise to much humor as the process of trying to determine the object progresses.
