after he sleeps with Stevie, they are both confused cause she thought he was gay. Stevie says she was confused cause she "only drinks red wine" and assumed David "liked red wine too." To which he adds
"I see where you’re going with this wine thing... Um, I *do* drink red wine. But I *also* drink white wine. And I’ve been known to sample the occasional rose. And a couple summers back I tried a merlot that used to be a chard0nnay, which got a bit complicated."
and Stevie asks if he likes ALL wines and he says "yes I like the wine and not the label"
