The Odd Couple

This episode is the first one that revealed a cruel streak in Cosmo's personality. His meanness to Wanda really began here, and recurred sporadically in following episodes. Many fans regard this change in Cosmo as being a "jump the shark" moment, prompting them to label him "jerky Cosmo" or "new-school Cosmo", and this unfortunate alteration precipitated the show's gradual decline in popularity.
