When I was a kid, I played this card game named "Mao" obsessively for a                                                    
   few weeks in the summer, and then completely forgot about it until                                                         
   today. Mao is an Uno variant, played silently, and the point of the                                                        
   game is to deduce the rules of the game - rules which are essentially                                                      
   made up by the dealer or local culture. It's a fun game. You never see                                                     
   anyone playing it at hacker conventions, which surprises me. One of the                                                    
   standard rules, which I'll give away here, is that if you talk, you are                                                    
   penalized by having to draw a card. Of course, until you can deduce the                                                    
   rules, you end up drawing a lot of cards.                                                                                  
   I guess my point is this: if you deal the cards, you can make the                                                          
   rules. Otherwise, silence is usually the best option.
