Dean Martin makes a joke about "Charlie's Angels" which aired opposite this roast on ABC.
Roaster Jimmie Walker was seen on "Good Times" earlier in the evening, at 8pm on CBS.
Lucille Ball had appeared several times with Danny Thomas on their respective series'. Ball also cast Don Knotts, Ruth Buzzi, Red Button, Orson Welles, Milton Berle, and Jan Murray, on her shows.
Ten years later, Lucille Ball cast Dina Dietrich in a role on "Life With Lucy."
Interestingly, although most famous for his series "Make Room for Daddy" (aka "The Danny Thomas Show"), there is no mention of it on the roast, only Thomas's latest sitcom, "The Practice."
