"In general, I think there are some things that require time before you can talk about them. Some stuff that happened over the summer, for instance - the Philando Castile shooting, Alton Sterling, the police officers in Dallas - there was no room for jokes. But there are, of course, the policies that have given us those events. Now, there's a lot of room for jokes there. When you're looking at something difficult to talk about, there's always a sideways way in that feels a little less personal to people. That's where the joke lives."
