Poochinski
Poochinski is a 1990 television pilot featuring a Chicago police detective (played by Peter Boyle), whose spirit is transferred into a flatulent English bulldog after he is killed in the line of duty. The canine detective then returns to solving crimes.
NBC decided not to pick up the series, but subsequently did air the pilot, on July 9, 1990. In recent years, the show's premise has been recognized as one of the most bizarre in television history.
