Chase Talbott III is a character from the comic strip Doonesbury. He was introduced shortly after Mark Slackmeyer realized that he was homosexual. For a while he invented an imaginary boyfriend for himself called Neil, who he pretended to talk to on the air. Later on he met Chase at a bar and he appeared on Mark's NPR show as a conservative foil to Mark's own liberalism. At first they pretended that their relationship was platonic, but Mark persisted in dropping hints that clued the audience into what was really going on.
