Okay, we'll give you that one. He was an actor. Not been seen much lately he was 84 (I think).
Mainly known for his TV role in the 70s(?) as "Felix Unger" on "The Odd Couple" with Jack Klugman. Two divorced men sharing an apartment. Based on the play and the movie that starred Walter Matthau and Jack Lemmon.
Please don't tell me you don't know who they were...
Matthau and Lemmon? Sure I know of them. Old guys in a lot of movies I haven't seen.
My knowledge of 70s tv shows is scant. Except for Star Trek.
