Mort is the wide-eyed mouse lemur from DreamWorks' Madagascar films, voiced by Andy Richter, who became a fan favourite for his obsession with King Julien's feet and his childlike voice. Clips of his laugh were lifted from the movies and shared on soundboards and short-form video apps, where the squeaky giggle became shorthand for anything small, cute or overly excited. Its brevity and clear character voice keep it recognisable even without the film scene, helping it survive as a reaction sound long after the original theatrical run.
