Hailing "from Parts Unknown," Zeph Marshack is the Walter Brennan-like uncle of Rose Marshack, a member of the indie rock band (The) Poster Children. He is fiercly protective of his niece, and has been known to threaten unspecified "wrath" upon those who cross his kin or giggle at his name.
Zeph's hobbies include slapfighting and spanking tethered rhinos at the local zoo. He is also prone to alcoholism, once admitting his preference to drinking straight vodka. Stating, "It's kinda like drinking hot water. It boins* the throat"
*a word most likely meaning "burns"
