Chuck Knipp (born 1961) is an American and Canadian (dual citizenship) drag queen and comedian best known for his alter egos, the characters 'Shirley Q. Liquor' and 'Betty Butterfield.' A number of videos of Knipp's Butterfield were featured on several different Youtube accounts until 2007 when most disappeared. In mid-2009 a number of videos were reuploaded to the site, many of them new. Many of them feature Butterfield relating her struggle to find a religion and/or church where she feels at home.

Entertainer RuPaul has long been a fan and supporter of Knipp. "Critics who think that Shirley Q. Liquor is offensive are idiots. Listen, I've been discriminated against by everybody in the world: gay people, black people, whatever. I know discrimination, I know racism, I know it very intimately. She's not racist, and if she were, she wouldn't be on my new CD." In her blog, RuPaul adds: "I am very sensitive to issues of racism, sexism and discrimination. I am a gay black man, who started my career as a professional transvestite in Georgia, twenty years ago."
