I think they did that with wine. They would pour some $500 bottle of wine into a glass and then in another glass was $6 Beringer or something like that. Then a third glass with some middle-of-the-road wine. Many so-called wine snobs could not tell the difference and some even picked the $6 wine to be the most expensive one. A true sommelier probably would know the difference but that takes years of specialized training.
Anyhow, I'm not buying the "$950,000 bottle of champagne thrown into a 150-inch TV" story either. I think the Clinton people just throw that crap out there to make us look like idiots. All too often, it works.
