This rhyme can also be found as "Monsieur Pouce" (Mister Thumb).

Notes

Monique wrote, "The 1st version is the one we know - 'we' being our group of friends. I remember doing it over and over again. The oldest of all my friends' kids was almost 2 years old (=30 years ago!) and he kept showing his fist and thumb and saying to my sister "Fais, fais!" ("Do, do!").

Game Instructions

To Start: The thumb is hidden in the fist.

(1) Knock three times on the fist and ask the question, "Petit Pouce, es-tu là ?"
(2) On "chut" (hush) put forefinger to the mouth.
