Deb was the first to catch this one:
In "Dress Your Family in Corduroy and Denim," the new book by David Sedaris, David mentions a time when he was living as a bum in his parents' house, smoking pot and listening to the same Joni Mitchell album over and over. Finally his father kicks him out - he assumes it's because he's an unemployed, pot-smoking bum, but later finds out it was because he was gay - and his sister agrees to let him move in with her, as long as he doesn't bring his Joni Mitchell album.
