What Happened on the Final Episode of ‘The Odd Couple’?

The Odd Couple has taken countless permutations through the years: a stage play, three different TV series, a cartoon, a made-for-TV special, and two Jack Lemmon/ Walter Matthau movies filmed 30 years apart. But the Odd Couple that most of us logged the most time with were Jack Klugman and Tony Randall, who spent five seasons portraying the uptight Felix Unger and the slovenly Oscar Madison from 1970 to 1975.

You might remember the fights, the mix-ups, and the earworm theme song (if it’s now stuck in your head for the rest of the day, my apologies). But do you remember what happened in the final episode? Why did Felix and Oscar finally stop sharing an apartment (and driving each other crazy)?
