It's Halloween. Want to hear Neil Patrick Harris get freaked out?

Thought so. You'll want to click on that play button above, and check out Neda Ulaby's All Things Considered piece on an L.A. haunted house — more of an interactive play, really — called Delusion.

If there's anything guaranteed to lift the heart of an NPR nerd, it's the sound of All Things Considered's Robert Siegel losing his composure. This is a news anchor, after all, who can deliver the song title "Party 'Til You Puke" with all the gravity of a president announcing the death of a hero. (No, really. This happened.)
