a made-up joke that makes sense

What did the cat say to the hamster in the library when they were about to read a book? “Hey, would you like to read my TALE?!”

Moomin made this up today at the library and told it to the librarian, who took 20 points of instant psychic damage from the cuteness. Her eyes rolled back in her head, chthonic beings rumbled deep underground near the San Andreas and Hayward faults, and geese all over the Bay Area turned upside down.
