Ford

Prefect, not Harrison.

Not to keep you guessing,

I'm an alien who saves

Arthur Dent from the dying

Earth, being demolished

for a freeway vying

intergalacticly.

If it wasn't for me

there would be no

Guide to the Galaxy.

There would also be

no introduction to

Vogon poetry.

Smabash trigonmy

Slob du nashtiy poo.

Hope that's agreeable 

to you but Vogans

have a knack

with a vowel or two.

By the way,

don't bother

saving the dolphins

they're smarter than you.
