Question: Who were the executive producers of the episode of The Simpsons called "Lisa's Pony"?
Context: The French Saddle Pony, also called the Poney Français de Selle, is pony breed developed as a sport pony for children and smaller adult riders.  It was initially developed in 1969 as the Poney de Croisement (Cross-bred Pony), and in 1972 a stud book was created.  In 1991 the stud book was closed and the breed renamed to Poney Français de Selle.  The breed combines a mix of French and British pony breeds, as well as Thoroughbred and Arabian blood, to create the horse seen today.  Due to the large number of breeds used to create the French Saddle Pony, there is not yet a defined set of physical characteristics for the breed, although all tend to be suited for competition in English riding disciplines, including dressage, show jumping and three-day eventing.  They fill a similar role as the British Riding Pony and the German riding pony. The American Walking Pony is a modern American breed of gaited riding pony.

The original breeding goal was to combine the smooth gait of the Tennessee Walker with the small size and refinement of the Welsh pony.  Any combination of the two breeds is acceptable for the registry.
