H2O 

The long foretold holy trinity of Philadelphia Phillies pitchers Halladay, Hamels, and Oswalt. Legend told of the year when these 3 pitchers would come together and win the World Series. Its even rumored that in Metal Gear if you enter the code Right-Left-Right X 2 (Halladay rightie, Hamels leftie, Oswalt rightie) you automatically win the game.

The order has to be H2O. For any other combination soon becomes unstable ( H2OK = Kendrick).

Even the Yankees cant stop H2O. Were gonna create a dynasty. After this season is over H2O is gonna go erode the Grand Canyon some more with curveballs

You: H²O
Science teacher then proceeds to whack you with a belt.
