George mentions that in darts the object is to reach zero. In most versions of the game, this is true, as the score starts at 301 or 501 for single player games, or 701 or 1001 for doubles, and the rules state that a player has to reach exactly zero with the score putting it to zero being a double score in order to be declared the winner. (Going past zero, reaching zero with a single or triple score, or reaching a positive score that puts reaching zero with a double impossible [like 1, 3, or 5] busts out the player, and their score resets to what it was at the end of their previous turn.)
George mentions that one change in basketball he would like is if the ball goes into the basket off another guy's head, it would be 25 points. About a decade later, MTV Rock n Jock Basketball would have a 25 point basket come out in the final 1 or 2 minutes, but it would be up about 20 feet in the air, and did not require the ball to bounce off another player for the points.
