Harry Dresden's 11th book, Turn Coat features a massive throwdown
on 'Demonreach', an island he has claimed as a sanctum
which features a potent group of people:
The White Council, the White Court, Harry, Billy, and Georgia (backed by the Za Lord's Guard and the Za Lord's Militia, headed by Toot-toot)
the skinwalker, Madeline Raith, and a whole host of summoned baddies.
Every single one of them (excepting Harry's followers) showed up to fight against Harry, to claim
who Harry knew to be innocent. Harry was using the situation to pit all of them against the baddies, and save a prisoner of theirs.
He tipped this, subtly, to Ebenezer by quoting an old cartoon. He says, "Wile E. Cyote, Sooooper Genius"
Aside from the obvious character reference, is Harry referencing a specific Wile E. Coyote cartoon? Ebenezer seems to recognize his quote to mean more than, "I have a plan that is likely to fail spectacularly, causing me grievous bodily harm."
