maybe you could try spicing up the mysteries. Put some peculiar characters in the rosary, like in the nativity scene, imagine one of the shepherds making funny faces, and the Christ Child giggling.
This may seem outrageous, but if it gets you to the rosary, I'm sure Mary will forgive you.
Thought of another one, put in a roman soldier that keeps falling on his face every time he has his nose in the air (during the carrying of the cross).
