This episode was a backdoor pilot for a proposed but unproduced series starring Bill Daily, who later this year landed the role of Howard Borden on The Bob Newhart Show (1972).
Although Chris takes a series of calls from Mack Truck Tarkas, who says he was cut from the Minnesota Vikings after tearing a hamstring and wore number 87 from 1967 to 1973 (which covers when this show originally aired), number 87 for the Minnesota Vikings was John Beasley.
