A Chilean version titled "Una Pareja Dispareja" began airing in January 2009 on TVN (which had aired the series during the 1970s). This version takes several of its cues from "Two and a Half Men", a Chuck Lorre-created sitcom with a similar premise to "The Odd Couple" (even alluded to the similarities between the two in the episode "Whipped Unto The Third Generation"). Some of the details taken from "Two and a Half Men" include Felix and Oscar being siblings instead of friends, as well as Felix being a doctor and Oscar a musician.
