Yesterday My Head Exploded

Yesterday my head exploded with a loud KA-BOOM!
Wanted to learn maths but found there wasn't any room
Couldn't fit more knowledge in
Now my neck just has a chin

Yesterday my head exploded with a loud KER-SPLAT!
Leaving me an empty space right underneath my hat
Tried to squeeze in one new fact
Straw that broke the camel's back

Yesterday my head exploded with a loud KA-POW!
Lost my ears, my nose, my mouth, my teeth, my hair, my brow
While my friends looked on and laughed
I sat headless in the class

Yesterday my head exploded with a loud KER-RUNCH!
Had to stop my studying, unable to eat lunch
Too much work too little play
Caused my top to blow away 

Yesterday my head exploded with a loud KER-POP
As my brain has disappeared this poem has to...STOP!
