Keep Im pasting here in slightly abbreviated form what I wrote at the Opera Project talk page earlier today I totally agree with  The resonance of artistic works beyond their original context and audience is an important cultural phenomenon Opera cartoons especially classics like the ones mentioned in this article parodies and even Seinfeld are often referenced in serious opera reviews and by opera houses and other cultural organizations themselves I know of at least one American opera house administrator who says that The Rabbit of Seville was his introduction to opera when he was  years old and hes never looked back Here are just a few examples   httpwwwandantecomarticlearticlecfmid   httpwwwdallasoperaorgtheseasonindexphp   httpwwwnprorgtemplatesstorystoryphpstoryId   httpwwwoperaamericaorgaudienceslearningcenterintromainstreamshtml  In my view the existence of parody andor use in popular culture is an indication of a works importance not demeaning or an insult to some kind of sacred art form Ive written in a similar vein here These kinds of sections just have to be watched to ensure that the other genres and works making the reference are in themselves reasonably high profile Its true that monitoring to remove tangential andor spurious references makes for more work but  a blanket ban and summary removal of outside cultural references can be a net loss to the article It helps to discourage inane listcruft if the section is written as prose not a simple list And giving it a section title like Cultural resonance outside opera or The Barber of Seville elsewhere rather than using the terms trivia or pop culture also helps When unsure of the cultural notability or relevance of some additions or if the list becomes too long it should not be summarily removed but transferred to the talk page apart from obviously uninformativesilly mentions where future editors can be requested to integrate the material into the text of the article The triviaadders tend to back off when you do that  Heres how I handled it in Cavalleria rusticana Theres been no trouble with that article since then Best
