Randy Marsh and Sharon Marsh (née Kimble) are fictional characters in the animated television series South Park. They are the most prominent set of parents on the show and a middle-class married couple who raise their 10-year-old son Stan and 13-year-old daughter Shelly in the fictional town of South Park, Colorado. Their first names are derived from the first names of series co-creator Trey Parker's parents, and Parker describes Randy as "the biggest dingbat in the entire show". According to the season 16 episode "Reverse Cowgirl", the Marsh home address was 260 Avenue de los Mexicanos until their move to a farm.
