Originally, yes. Later they changed it to Schaefer. One of many continuity blunders in The Odd Couple but it's still one of the best sit-coms ever, in my opinion.
@@ShibaInuElonMusk Originally, Gloria's maiden name was Schaefer in the episode where Oscar proposed when Felix lost his voice (Season 2, Episode 16, "Speak For Yourself"). At the end of Season 4 Episode 5, "The Odd Holiday," when Felix tried to help Oscar and Blanche's marriage, he destroyed his own, that's when the writers used Fleaner (Fleener) as Gloria's maiden name. Always continuity blunders in many sitcoms, but I agree. It was also one of my favorite shows as well.😎
