I read a book last year (Song for a Whale) about a Deaf girl who would play a game with her grandfather where they would create a story together while using the same hand shape all throughout. So maybe they would make a fist, or ann open palm, or a “y” shape and then the story was created using signs that used that hand shape. If you couldn’t continue the story with the same hand shape you lost. Not exactly a pun but I thought it was interesting.
