Philip "Pip" Pirrip[2] was an often mistreated, awkward English orphaned exchange student, who was heavily based on the protagonist with the same name from Charles Dickens' novel, Great Expectations. He was voiced by Matt Stone and first appeared in the Unaired Pilot before making his official series debut in the Season One episode, "Cartman Gets an Anal Probe". He was a major character in the early seasons, but was written out of the show and then killed off in "201".
