Neil Patrick Harris is the latest celebrity to participate in Vogue's "73 Questions," and we have to say, his interview is very interesting. While answering questions about everything from where he thinks Doogie Howser is now (hint: in rehab) to what kind of father he is to twins Gideon and Harper, the actor shows off his insane home, which has a movie cinema, the actual booth from How I Met Your Mother, and a bar. While we usually learn a few fun facts about our favourite celebrities through these videos (did you know NPH has a guest book at his house for visitors to sign?), he really lets you into his sweet home life and answers some hard-hitting questions. Neil's husband, David Burtka, even makes a fun cameo as they answer questions at the same time. Now, when can we come over?
