Debbie Downer is a fictional Saturday Night Live character who debuted in 2004, and was created and portrayed by Rachel Dratch. Evolving from the character's popularity, the name Debbie Downer eventually became an established slang phrase referring to a pessimistic person who frequently adds bad news and negative feelings to a gathering, thus bringing down the mood of everyone around them. Dratch's character would usually appear at social gatherings and interrupt the conversation to voice negative opinions and pronouncements. She is especially concerned about the rate of feline AIDS, a subject that she would bring up on more than one occasion, saying it was the number one killer of domestic cats. First appearance in 2003–04 season The first appearance of Debbie Downer was on May 1, 2004, with guest host Lindsay Lohan. Debbie and five family members—played by Lohan, Jimmy Fallon, Dratch, Amy Poehler, Fred Armisen, and Horatio Sanz—are eating breakfast at a restaurant in Walt Disney World. While the family makes small talk, Debbie makes negative comments on worrying current events such as feline AIDS, followed by a knowing look at the camera and a cartoonish "wah-wah" sound made by a muted trombone. In the sketch, everyone on camera breaks character and begins to laugh because of both the "wah-wah" sound effect—which the cast did not expect—and Dratch flubbing a line early on and correcting herself. The sketch was listed at number 99 as part of TV Land's "Top 100 Most Unexpected Moments in TV History." 2004–05 season Debbie Downer appeared in a sketch in the 2004–05 season opener with Ben Affleck as the guest host. The cast members who appeared in this sketch were more composed and did not laugh out loud at Debbie's pronouncements. This trend continued throughout the rest of the season. In future airings of the Affleck episode, the live Debbie Downer sketch was replaced by the dress rehearsal version, along with an opening title card explaining that the dress rehearsal "worked better." In the dress rehearsal, the cast all cracks up just as they did in the Lindsay Lohan episode. The character appeared two more times that season: once at Thanksgiving dinner (with Luke Wilson as host) and another at the Oscars with Hilary Swank (playing herself). The latter sketch revealed that Debbie babysat Swank when Swank was a child. Will Forte appeared in the sketch as Swank's then-husband, Chad Lowe. 2005–06 season In
