What is messy roommate on the odd couple?

The Odd Couple is a sitcom about two roommates - Felix Unger (played by Tony Randall) and Oscar Madison (played by Jack Klugman). Felix Unger is a neat freak while Oscar Madison is a slob. The show frequently portrays the trouble Felix faces living with an extremely messy roommate.

Oscar's slovenly habits include leaving the apartment in disarray, dirty dishes piled up in the sink, clothes piled on the floor, and newspapers strewn everywhere. Felix, on the other hand, is a meticulous person who cannot stand the mess that Oscar creates.

Despite their differences, the two roommates managed to maintain their relationship, though Felix's complaints about Oscar's messiness often result in humorous situations.

Overall, the messy roommate trope is used as a common theme in The Odd Couple to create a comedic situation between two characters with drastically different personality traits.
