Just how did Clark keep track of what he did as whom and when to use which pronoun? Must be another super-skill.
Incidentally, both Bud Collyer’s (radio) Superman and George Reeves’ (television) one did occasionally slip up -- enough to provide a bit of levity to the audience, but never enough to give themselves away completely to the people with whom they were speaking.
This bit of fluff was un-beta-ed.
As always, all comments welcomed.
