LORELAI: We’re running out of coffee … I got it.
LUKE: Do you know how?
LORELAI: Do I . . . ugh . . . I am Cathy Coffee, mister, the bastard offspring of Mrs. Folger and Juan Valdez.
Cathy Coffee
I think a fictional coffee mascot that Lorelai has invented and is now personifying.
Mrs Folger [pictured]
Mrs Olson, or “The Folgers Coffee Woman” was in a string of television commercials for Folgers Coffee during the 1960s and ’70s. Mrs Olson was a Swedish neighbour who always recommended a cup of Folgers Coffee to other people in the commercial. She was played by an actress named Virginia Christina, born Virginia Ricketts (1920-1996).
Juan Valdez
A fictional character who has appeared in advertisements for the National Federation of Coffee Growers in Colombia since 1958. He is an icon for both coffee and Colombia. He was portrayed by a Cuban actor named José F. Duval until 1969, then by Colombian actor Carlos Sánchez. Since 2006, Juan Valdez has been portrayed by Carlos Castañeda, a coffee grower from a small town in Colombia.
