The drug-addled, skirt-chasing Neil Patrick Harris from Harold & Kumar Go to White Castle wasn't the one out to play last night at Broadway Backwards III. As part of an evening of performances to benefit the Lesbian, Gay, Bisexual, and Transgender Community Center, Doogie sang a duet with his partner, David Burtka. But the high-minded goals of the evening didn't stop him from dishing about his, um, high-minded role in the much-anticipated sequel, Harold & Kumar Escape From Guantánamo Bay. "It's the very next day, so I'm still the same Neil Patrick Harris you saw before," the How I Met Your Mother star explained. "I have not attempted rehab. I might have gone on another bender since you've seen me. Maybe not on the same drug. Maybe a new drug." Speaking of new drugs, what was it like riding on a unicorn to pose for the movie's posters? "It was a little hard.… I had to ride it without a saddle, and it was in a green-screen room, and I had to ride it up a ramp and turn around," Harris said. "And this unicorn is very unfamiliar with a crew and green screen, and you don't have a saddle to hold on to. So there was lots of calming, nurturing touches.… It was very Horse Whisperer–y." Oh, Doogie, you can whisper to our unicorn any time. —Brian Moylan
