Mrs. Banshow

Name

 * Banshow comes from the Chinese "胖瘦" (Pàng shòu) meaning "Fat Thin." A reference to her phisique compared to that of her husband.
 * Petunia comes from Petunia Dursley from the Harry Potter canon. The Banshows are partially based on the Dursleys.

Leitmotif

 * The Banshow's theme, Mr. & Mrs. Banshow - The Modern American Couple, is a misnomer. It says they are a modern couple, but since they are from the 19th century, this is not very accurate.
 * Mr. & Mrs. Banshow - The Modern American Couple is the only theme in the series that's named after someone, but is also used for many other people
