The Odd Couple (1970)

Show generally

Continuity mistake: In the opening credits of the first season of The Odd Couple, Felix is moving in "with his childhood friend", Oscar. In a subsequent season, a storyline does a flashback to say that Felix and Oscar met when they were both jurors at a trial. Soon after, they cut the word "childhood" on most of the openings after people called the station to mention the mistake.

Trivia: Although Jane Dulo plays Jack Klugman's mother, she was only five years his senior.
