Money For Being Not-First 
Play arcade mode with two people/controllers. Finish the race with only one player, 
leaving the other player at the starting line. Until player 2 finsihes the race, the 
race continues. 

Use the first player to hit all the opponents that have already passed the line. 
Player one cannot finish first, as that prevents him from moving around to hit 
other racers.
