This IS hard. What came to mind for me was Lane Smith's IT'S A BOOK. The title isn't provocative, but the whole thing seems aimed more at the adults than the kids.
Some titles that adults might think funny before young kids would:
Snappsy the Alligator (Did Not Ask to be in the Book) by Julie Falatko
Wolfie the Bunny by Ame Dyckman
Red: A Crayon's Story by Michael Hall
Interstellar Cinderella by Deborah Underwood
Play on words titles:
Duck, Duck, Dinosaur by Kallie George
Outstanding in the Rain by Frank Viva
Mother Bruce by Ryan T. Higgins
The Sleepless Knight by Ashley Halil
Fright Club by Ethan Long
LGBTQ theme: Worm Loves Worm by J.J. Austrian
