The song "What Is Love" is originally by Trinidadian-German singer Haddaway, released in 1993. It became widely popular in Europe and beyond. Will Ferrell is famously associated with this song through his role in the recurring "Roxbury Guys" sketches on Saturday Night Live (SNL), where he and Chris Kattan played characters who bobbed their heads comically to this song as they went clubbing. These sketches inspired the 1998 comedy film "A Night at the Roxbury," starring Will Ferrell and Chris Kattan, which prominently features "What Is Love" as a key part of its soundtrack and theme. Thus, Will Ferrell is linked to "What Is Love" mainly through comedic performances in SNL sketches and the movie "A Night at the Roxbury," rather than being the original artist of the song. The song itself is a Eurodance hit by Haddaway known for its catchy question about love and has become iconic in pop culture partly due to the Roxbury sketches and film.
