Yes, D is for the Duck and the Dodo.
("The Duck and the Dodo," by the way, would be a killer name for an English-style pub. I'm just putting that out there.)
(You'd better click and enlarge, for the joke.)
William the Conqueror, whose cause was favoured by the pope, was soon submitted to by the English, who wanted leaders, and had been of late much accustomed to usurpation and conquest. Edwin and Morcar, the earls of Mercia and Northumbria, [...] declared for him: and even Stigand, the patriotic archbishop of Canterbury, found it advisable —
At this point, the Duck interrupts, asking what the archbishop found.
"He found it," the Mouse says. "Of course you know what it means."
And that's how we get to the dialogue that I quoted in my drawing. It still makes me chuckle, and I think I probably say "When I find a thing, it's generally a frog or a worm" once or twice a month. Mike can probably confirm that for you.
This was an easy drawing for me to put together. I think I must have drawn my share of ducks and dodoes in the past.
Next week: a little tribute to one of my "Always Fun to Draw" bros. (Aw yeah.)
