Quadruple couplet about my Pokemon battle on February 26, 2013 (FICTIONAL)

[KidIcarus]

My name is ash ketchum
Pokemon? Yeah I catch them

My best one is Porygon
Want a root beer? let me pour you one

Sike! Mewtwo that was poison
That'll teach you not to mess with me son

Have fun with your diarrhea
While I'm just here playing my brand new lira
