The dramatic trope of this story, a spouse or fiancé disguising himself to test a woman's fidelity, structures Da Ponte's libretto of Mozart's opera Cosi fan tutte and was in fact ancient when Ovid recounted it in his story of Procris in the Metamorphoses.
Buddy's mention of Wayne King is an ultra rare example of the series, generally considered timeless, using then-contemporary pop culture references. King was a songwriter and bandleader whose waltzes were popular on American radio in the 1930's, 40's, and 50's, but his last studio album released in 1962 (same year this episode came out) and his popularity quickly waned thereafter.
The plot of this episode is lifted entirely from the Ferenc Molnar play "The Guardsman," which was filmed by MGM in 1931 and remade as The Chocolate Soldier (1941). The conceit (an actor attempting to seduce his own wife while disguised as a foreigner) was also utilized as a major plot point in The Barkleys of Broadway (1949). The basic plot was utilized once again in 1984 with Lily in Love starring Christopher Plummer and Maggie Smith.
