"Nathan Fillion has featured in the latest episode of Neil Patrick Harris&amp;#039;s Puppet Dreams. The Castle actor appears in episode two of the How I Met Your Mother star&amp;#039;s comedy web series as a doctor.      Puppet Dreams features Patrick Harris&amp;#039;s daydreams dominated by puppets. &amp;#039;Doctor&amp;#039;s Office&amp;#039; sees Patrick Harris reunited with Fillion, following their previous appearance in Dr Horrible&amp;#039;s Sing-Along Blog. Speaking about the episode, Patrick Harris told The Hollywood Reporter: &amp;quot;We planned to be much more like a Muppet Show sketch where we had elevated sets and a bunch of puppeteers were down below and a human actor that was interacting with the puppets as if it was a live variety show. &amp;quot;It was intentionally blue, but was intentionally light blue. The whole joke at the end is none of it is relating to genitals at all. &amp;quot;We pushed the boundary for sure. That&amp;#039;s kind of the Muppets, [Jim] Henson-style of comedy that I always loved. The double entendre, if you will.&amp;quot; Neil Patrick Harris is currently writing a &amp;quot;nonlinear&amp;quot; autobiography. "^^<http://www.w3.org/2001/XMLSchema#string>
