(on seeing a sweet little white-haired old lady working in her immaculate yard...)
"Old people like to have nice yards. (silence for a few beats...) I think... I think it's because they want people to look at their yards and think they're young. Old people have white hair and wiggly skin and they think if they have a really beautiful yard with flowers and everything, people will look at the pretty yard and think "Oh, some young pretty person must live in that house!"
