His birth father died when Brent was less than a year old, so he took his adopted father's name "Mintz" from 1955-1975 before finally reverting back to "Spiner."

This game show is definitely showing its age, and I do find it amusing that they used not just such an ordinary-looking host, but one who also looked about ready for the retirement home. But he does in fact do a fine job I think, and the show itself has a very interesting premise, one in which a panel must try to pick between two imposters and a genuine person.
