When Frasier picks up the call from Brandy he accidentally calls her Randy before she corrects him. This may be an in-joke about the celebrity caller "Steve" he just hung up with who was voiced by country singer Randy Travis.
We learn Maris comes from a Roman Catholic family. Niles (David Hyde Pierce) and Frasier (Kelsey Grammer) discuss her "first communion" trip to Rome and her father smoothing things over with the Pope, after she took a crucifix.
Frasier (Kelsey Grammer) mentions poi ramekins. Poi ramekins are small dishes in which Poi is served. Poi is a Polynesian staple food made from the kalo (or taro) plant.
The title of this episode is a play on "a word to the wise", the Anglicized form of "verbum sapienti satis est".
One celebrity caller in this episode is Faith Prince (Brandy) who, after being told to do so by her boyfriend Jerome (Harris Yulin), calls in to ask Frasier (Kelsey Grammer) if she should marry him. This is pay back for Jerome helping with Maris' ticket problem and part of his plan to get Brandy to marry him. The other celebrity caller is Randy Travis (Steve), who calls up to discuss his efforts to lose weight.
