Randy Marsh

Dr. Randall "Randy" Marsh is the son of Granpa and Grandma Marsh, the half brother of Jimbo Kern, the former husband of Sharon Marsh and the father of Stan and Shelly. Despite being a geologist with a doctorate, he is generally portrayed as an absent-minded idiot, driving many episode plots in the later seasons, though this was later revealed to be due to him being unhappy over his marriage. In "Your Getting Old" he divorced his wife and moved away.

Appearences
Randy wears a blue colored shirt with chest pockets on each side and dark gray trousers. Under his jacket, it is implied is a white shirt. His left-side pocket usually has a yellow, a red, and a blue pen, plus some white paper pinned in. He has thick, black hair with parted bangs, and a thick black mustache, both of which seem to evoke a 1970s hairstyle. In early episodes, though, his hairstyle was somewhat different (see left). Up until "Chickenlover", he didn't have a dimpled chin. But in and after that episode he mysteriously developed one (of course, in the early stages of South Park, many things changed).

At bedtime, Randy wears deep blue pajamas with a long-sleeved shirt, and gray slippers. Though he appears slim and in shape when clothed, he is rather flabby, and has a protruding stomach, as seen when naked. Randy also has prosthetic testicles following the removal of his own due to his self-induced testicular cancer.

In his special occasion outfit, which consists of a white dress shirt, a light blue tuxedo, blue pants, and a gold tie, he has a gold handkerchief in his blue coat pocket.

Personality
Randy is often portrayed as an intelligent but simultaneously dim-witted, quick to think, naive man, while all the same a caring, doting father. However he is also obsessive and when he gets obsessed over something, his personality turns to the exact opposite. He becomes immature, childish, and dumb during the obsession phases. He has a habit of being led astray by new fads or events, like many of the characters. All the same, he has also been known to go completely against such things, though his reasons are usually selfish and immature. He will also try to do a heroic thing, but will then be distracted due to a selfish reason as seen in "Insheeption". However, this was caused by Mr. Mackey because Randy ignored the psychaiatrist's wanting about Mackey's dream being so unstable. Randy also seems to drink a lot of coffee, shown carrying a cup in most episodes he is in at one point or another.
