I think it's "Jon" Voight, but, other than that, I listened to him on the commentary to the "National Treasure II" DVD, and laughed out loud when he recommended Newt Gingrich's book during the commentary. The other commentator (director?) was so befuddled he didn't know what to say. Hehehe.
It’s a Seinfeld episode: George buys a car because it was owned by a John Voight [who turns out to be a dentist.] The [correct] spelling of Jon is part of the gag.
