In Are you lovin' it?, Tom Asacker has a great post elaborating on David Ogilvy's comment that "Agencies waste countless hours concocting slogans of incredible fatuity."

For every vaguely memorable slogan, there are countless utterly forgettable ones. Tom lists ones McDonalds have used over the years as evidence, and also suggests this list of company slogans. Barely a spark of memorability among them.
