The way you hold your wine glass demonstrates what social class you are in?
Please. They're talking about how you hold a wine glass--which makes all of them effete elitists, as far as I'm concerned.
They didn't have a picture showing somebody drinking directly from the box! I feel I'm putting on airs if I drink it from a glass that used to hold jelly.
Tip to Instapundit.
UPDATE: Thanks to Stones Cry Out for the link. And yeah, what about wine helmets?
