Grandma Marsh

Grandma Marsh is Randy and Jimbo's mother and Stan & Shelly's grandmother. She makes her first appearance in You have 0 Friends.

Appearance
Despite her failing health and the suggested age of Grandma Marsh, she appears to remain relatively younger than Marvin. She has grayish white hair and glasses. However due the fact that Grandma Marsh has only appeared as a digital avatar character in the techno-world of Facebook, her appearance may not exactly be accurate to her current state. Also she is not seen wearing normal attire, but instead she is seen wearing a Tron-like costume of glowing technology.

History
When Stan's friends Cartman, Kyle and Kenny create a Facebook for him against his will, Stan begins to become assaulted by Facebook-type requests from everyone around him, including his grandmother. Apparently suffering from some sort of illness and hospitalized, Grandma Marsh spends much of her time on Facebook to keep in-contact with her family and friends. However when Stan does not immediately "friend" her, she contacts her son Randy who then demands that he pay attention to his grandma's Facebook status.

Later when Stan is literally 'sucked into' Facebook, a digital avatar of his Grandmother is seen interacting with all of his other Facebook friends, at a digital party created by his now sentient Facebook page. Once Stan defeats his Facebook page in a game, she and everyone else is de-friend-ed.

Trivia

 * Grandma Marsh has two sons: Randy Marsh and Jimbo Kern.
 * Due to the fact that Grandma Marsh does not live with Stan's grandfather, Marvin Marsh, and because he once had a sexual encounter with a contortionist in Quintuplets 2000, this would imply that she and Marvin are divorced, unless of course Randy was an illegitimate child born out of wedlock.
 * Due to the fact that Jimbo Kern is 51 and Randy Marsh is 38, this would imply that her ex-husband Marvin is her second husband, assuming that she did indeed marry their fathers.
 * Grandpa Marsh is listed at being 102 years old, however Grandma Marsh looks considerable younger than him. Due to the fact that Randy is 38, Grandpa must have been roughly 64 when he impregnated Grandma. She was most likely considerably younger.
 * The fact that Grandma Marsh is suffering from a debilitating illness causing her to be in the hospital, might also explain why she has not appeared before this episode.
 * She was mentioned by Stan in Quintuplets 2000 and Margaritaville but no name was given.
