2 people guest-starred in 1 episode of Kojak -- Dennis Patrick (Jason McGuire, Paul Stoddard) in 1974; David Selby (Quentin) in 1976.
I watched it not too long ago! Also Paul Michael, Abe Vigoda, Emory Bass, Norman Parker, Gail Strickland, John Beal... Grayson Hall's appearance is one of my favorites. Blair Brown and Michael Cavanaugh, too. Ken McMillan did 3 eps, btw. Anyhoo...
L is for lugubrious, for DS' lugubrious quality. Love love love PennyDreadful's pronunciation of the word in her Shilling Shocker that's devoted to DS.
