Another of MTV's reality-based sitcoms -- or was it a sitcom-based reality show? -- Run's House focused on the family of rapper-turned-minister Joey "Run" Simmons, of Run-D.M.C. fame. Preferring to be called "Rev Run," the protagonist was the benign ruler of a rambunctious but good-natured household consisting of his wife, Justine, and children, Russy, Diggy, Angela, JoJo, and Vanessa. Holding the "plot" together was Run's ongoing effort to keep his brood reined in while busily recording his comeback album (a situation surprisingly close to that of the like-vintage TLC documentary series Tuckerville, which featured Tanya Tucker and her family). It so happened that his kids also wanted to be in showbiz, an aspiration that Run was fully in favor of provided they kept their grades up and their heads on straight. Run's House began running on October 13, 2005.
