In 1970, the members of Monty Python's Flying Circus came up with one of their most beloved and inadvertently prescient sketches, in which a customer in a restaurant desperately tries to order something that doesn't contain SPAM, only to find that pretty much everything on the menu features it. In the course of his ill-fated dinner, a nearby party of Vikings "“ hey, we did say it was Monty Python "“ breaks into song: "SPAM, SPAM, SPAM, SPAM, SPAM, SPAM, SPAM, SPAM, lovely SPAM! Wonderful SPAM!" Clearly, repetition is funny. Also, and more relevant for the relationship between SPAM and email, repetition is annoying.
