Donkey Kong Junior (Arcade)

DK's time machine

Start a 2-player game. Have player 1 play through normally until he dies. When player 2 starts, move DK Jr. to the right edge of the starting platform so part of him is off the edge. Wait for a blue Snapjaw to come down the vine to your right, and when his mouth touches the end of the vine, jump to the right and you should hit the water and the Snapjaw at the same time. If you timed it correctly, DK Jr. won't do his death-temper-tantrum; instead, the game starts both players back to their previous life, but with all the points you've already earned! If you can do this trick consistently, player 1 can rack up an incredible amount of points.
