My sister and I both took French in school.  Any time the subject came up our father would chirp “mettez le crayon sur le pupitre”.    Put the pencil on the desk.

Years later, when the subject of French came up in my uncle’s house my uncle immediately chirped “mettez le crayon sur le pupitre.”  My sister and I both laughed.   

My uncle explained:  we had the same French teacher.
