The X and Judy show can trace its roots to the 16th-century Italian commedia dell'arte. The figure of X derives from the Neapolitan stock character of Pulcinella. He is a manifestation of the Lord of Misrule and Trickster figures of deep-rooted mythologies.

The classic ending of the show has him upending the Devil himself, exclaiming "Huzzah huzzah, I've killed the Devil!".
