Factual error: Sir Roderick has moved his psychiatric clinic to New York because the BMA wouldn't approve of his methods. Although we don't get exact dates for the episodes, since prohibition was in effect in the last episode and Puttin' On The Ritz came out in 1929, we can presume it's the late 20s/early 30s. The AMA wouldn't recognize psychiatry as legitimate medicine until the 1940s. Sir Roderick wouldn't have had any better luck in America.
