Jerry Van Dyke has appeared many times on this series as Tag, the father of Patricia Heaton’s Frankie. But tonight, he shows up with a familiar special guest star in tow: His brother Dick Van Dyke, playing Tag’s long-estranged sibling. The two real-life comedy brothers first shared TV time when Jerry guest starred on his older brother’s The Dick Van Dyke Show back in the Sixties – and five decades later, little brother is returning the favor by bringing big brother to The Middle. Dick is 89 now, and Jerry 83, and fans who remember the elder Van Dyke’s classic TV sitcom will get special joy out of one of tonight’s sight gags. It involves an ottoman.
