Sasuke
There was once a strange fellow,
to whom Haruno Sakura said "hello",
Within his pocket he pressed a button
Which caused her head to burst like muffins
a quite curious teacher said
what caused the bursting of my student's head?
Uchiha Sasuke gave a smirk
and slyly began to lift his shirt.
"Sasuke what nuisance is this!
I'll have to greet you with my fist!"
