Kirby (Brian Klugman) is the teenage son of Lana and Bob Gardner, and sometime employee of KACL. He is briefly tutored by Frasier, with whom he develops a father-son relationship in the later portion of his appearances. He also does odd jobs for Niles. Kirby's wild hairstyle has been compared to Sideshow Bob's. Kirby is smitten with Roz Doyle, leading Frasier to manipulate Roz into escorting Kirby to the latter's high school prom as an incentive for Kirby to study and acheive good marks.
