Here's a brilliant example of advertising logic: "When pizza's on a bagel, you can have pizza anytime." Oh, reaaaallly? My teacher friend Jill used this commercial as an example of the rhetorical figure enthymeme, a three-part deductive argument with an unstated assumption which must be true for the premises to lead to the conclusion. To put it simply, why the hell does putting pizza on a bagel allow you to eat pizza anytime???
