What about Bob is a 1991 American black comedy film directed by Frank Oz, and starring Bill Murray and Richard Dreyfuss. Murray plays Bob Wiley, a psychiatric patient who follows his egotistical psychiatrist Dr. Leo Marvin (Dreyfuss) on vacation.

Before going on vacation, self-involved psychiatrist Dr. Leo Marvin (Richard Dreyfuss) has the misfortune of taking on a new patient: Bob Wiley (Bill Murray). An exemplar of neediness and a compendium of phobias, Bob follows Marvin to his family's country house. Dr. Marvin tries to get him to leave; the trouble is, everyone love Bob. As his oblivious patient makes himself at home, Dr. Marvin loses his professional composure and, before long, may be ready for the loony bin himself.
