Harry Mills is a sports writer, photographer, and journalist for the Elwood City Times. He and Buster's mother Bitzi both encountered each other in "Bitzi's Beau," and became a dating couple. At first, Buster thought he might be an alien from outer space, but turned out to be a very nice man, and that he works where Bitzi works. He and Bitzi later broke up in "Bitzi's Break-up", but stayed friends. He returned in the episodes "Baseball Blues" and "Molina's Mulligan."
