Can you remember if Jack Klugman was ever a guest on these series?

Many people know Jack Klugman from his role as Oscar Madison in The Odd Couple. The Odd Couple had a simple but hilarious premise: Two men, a neat freak and a slob, have to live together despite their differences. And boy, do they make one odd couple.

Tony Randall played the role of Klugman's co-star in the series, Felix Unger. After five seasons of The Odd Couple, Jack Klugman went on to do other things. The Odd Couple also wasn't the star's first role. 

Let's test your knowledge of one-half of The Odd Couple duo. Can you remember what other classic TV shows Jack Klugman is in? Good luck!
