In addition to playing "Miguelito" on "Green Chaparral," Dr Sloan's card playing partner Webster also supposedly played "Lieutenant Flynn" on "Jerry O's." Henry Darrow actually played Manolito on The High Chaparral (1967) and Lieutenant Quinlan on Harry O (1973).
Lawrence Pressman and Henry Darrow are reunited in this episode. They were in McMillian and Wife episode Requiem for a bride on in 1975.
In the card game Dr Mark Sloan recognises Webster (played by Henry Darrow) as having played a character called Miguleto in a series called Green Chaperal. In real life Henry Darrow played Manolito in High Chaperal.
