Spam, spam, spam!
This popular sketch takes place at a cafe in which all the menu items feature Spam (a variety of tinned pork) among its list of ingredients. In some cases, the Spam is listed more than once as part of the dish. A customer attempts, without much success, to get a breakfast without Spam. Eventually, a group of Vikings at the cafe drown out all conversation by chanting more and more loudly the word "Spam". The phenomenon, some years later, of marketers drowning out discourse by flooding Usenet newsgroups and individuals email addresses with junk advertising messages was named spamming in honour of this sketch.
