Bishoujo Baseball Gakuen
A strange baseball variant game where you must guess the position, type, and speed of the pitch to be served, and try to get as many of your runners home as possible. At certain runs, the pitcher girl strips, a new round beginning once she is naked and with her assuming a different pose fully clothed again. Three outs gives you a game over and instead whips the top off of one of your female teammates. Somehow I get the feeling this game was partially inspired by Charlie Brown and the incidents when he would get a pitch knocked back at him.
