Not that I have such a book, but I'm curious: Is jest allowed in a humorous work's query letter, or will it always be taken seriously (and thus interpreted as a sign of a delusional author)? I've seen people labeled as nitwits on the blog for making statements in query letters that I thought were meant as faux pretentiousness for satirical reasons. What if it's over the top? For example, would something like the following be taken seriously:
---ATTACK OF THE FIFTY FOOT POODLE has received glowing endorsements. Dave Barry said, "We're sorry, we're not home right now. If you would please leave your name and number, we'll call back as soon as possible."
John Cleese said, "Who are you, and why do you keep calling me?"
Terry Pratchett said, "Beep! Beep! Beep!"
(little note at end: "Certified 100% real jest by the USJA.")
Humor is very very difficult to do well in a query letter. However, your example above would work because of the Dave Barry thing. Clearly that's a joke. Even the normally sober sided and humor impaired Miss Snark recognizes that.
In the Snarkives is a post about humorous queries. A writer sent me a very funny parody of a query. I posted it next to an actual query. It was pretty hard to tell the difference. In fact the parody writer didn't know that I got the joke and was a bit taken aback (or so he said on his blog).
Sardonic and sarcastic and deadpan humor are the hardest to convey. I know this first hand from the blog. I'd advise letting your pages convey the humor and playing it straight in the query.
