The title is, of course, an extract from the famous Gilbert & Sullivan opera:

I am the very model of a modern Gungan General,
I've information vegetable, dinosaur, and mineral;
I know the Queens of Naboo, and I led the fights historical,
From Tatooine to Coruscant, in order categorical.

I'm very well acquainted, too, with matters Senatorial;
I understand accoutrements, both simple and sartorial,
Regarding eating humans I am teeming with a lot o' news -
With many cheerful facts about the flavour of those nice Naboos.
