Why is his head...

"It looked like a section of the Death Jar, I could have sword i
just saw Crebrum waving at me..." said Dean.
"The Evil one? ....What am i saying they are BOTH evil twisted
indavioduals..." said Phil
"Can we pursue them?" asked Alota
<END SNIP>
"In this..." started Dean, "Actually, I've been wanting to see what
this baby can do . Strap in."
"We're going to die, mouthed Alota to Phil.
Dean pushed the throttles right to the limits of their slots. The
Raven leapt forward, and slung round in pursuit of the Death Jarette.
"Hey, this is pretty fast for something this size." said GP, looking
over Dean's shoulder at the dials. "I wonder how the thrust to ton
ratios were worked out..."
"Didn't I tell you to buckle up?
"Why, yes.." started GP,
The Raven was hit head on a vial from the Death Jarette's Ointment
cannon. The impact, thankfully had little effect on the large ship.
"Ok, any thoughts on whether or not that vial will have any effect
on us?" said Alota.
"Well, obviously it will." said Dean, pompously. "For it will have
been designed to somehow overcome ship armour, possibly using the
Gregoian method of matter displacement in the 3rd theroem's
capabilities."
"I doubt it," said Tara, "The 3rd theory has several gaping holes,
but, more importantly, I think we need to find out what the effect
on us would be from this ointment."
"Well," said Alota, "As we are discussing Gregorian motion in the
3rd Thereom..."
"I thought it was the 2nd Thereom." countered another member.
"Well, precisely." said Alota, "I reckon it's made our brains
bigger."
"What's up with GP?" asked Tara, bending over him as he writhed on
the floor, screaming.
"Somone! Make it stop!" yelled Dean, trying to pilot and avoid
anymore vials.
"I can't." yelled Tara back.
"Because he's so smart." started Phil,
"Well you're not." said Alota, "Starting a sentence with "Because"?
honestly..."
"Well, as he is so intelligent, his brain was already bigger, so
when it enlarged, there's no room."
Suddenly, GP went quiet, and started shuddering, his eyes rolling,
his head juddering on the floor.
"HE'S GOING TO BLOW!!!!" yelled Alota, throing herself behind a row
of seats.
She was wrong.
GP didn't just blow.
He BLEW like a gas geyser, His head sprayed all over the inside of
the Raven. And the Raven was big. Dean's windshield was coated with
a film of blood and flesh, his head and cockpit covered with the
former pieces of GP's hypothamalus.
The frontal lobes covered Tara, who hadn't had time to duck for
cover, whilst MP was covered all over in bits of brain and gunk.
Phil himself was immediately coated in his doppelgangers right
hemisphere, whilst the rest of the left hemisphere landed with a
plop on the seat Alota was hiding behind.
"SOMEONE GET A CLOTH!" yelled Dean, "I CAN'T SEE! AND WE WERE
GAINING!"
"What?"
"EVERYBODY DOWN!!!!" yelled Phil, as teh Raven crashed into the
Death Jarrette...
Dean "Blind - so probably driving better" Thomas
