BTW, about the Damar hangover picture...I actually had a serious comment to make about that scene. Unlike a lot of depictions of drunkenness that make it look funny or otherwise "attractive," I applaud that depiction for showing just how ugly the problem of alcoholism can be, and just what a toll it can take on a person's life. There was absolutely nothing glamorous or funny about that hangover. And that was a good thing.
You're absolutely right. Really - and I'm being sincere here - this is one case where the hair is pretty darn important. I mean...a dishevelled Cardassian! I don't know if we ever saw anything else quite like it.
