hunh!
After 13 years, I realized in the ep Home, we find it's canon that Sir (remember when we called him Sir? Good times, good times...) smoked. I was surprised! I've watched the ep umpty-million times, and this was the first time I realized that the pic of John and Mary? He's holding a cigarette. And lookin stoned, so there's that, too. I laughed, and I filed that shit in My Big Book of Supernachul Fax. :D
