"One Day S'more" is a song from the Cookie's Crumby Pictures segment, "Les Mousserables." The song parodies "One Day More" from the musical, Les Misérables.

After Cookie Monster (as Jean Bon-Bon) shares his cookies with everyone, one friend (a caricature of Marius) supplies everyone with marshmallows to make s'mores as they sing the grand finale.
