I just spent the last week going back and forth to Los Angeles for the 25th Anniversary William S. Paley Television Festival. Man, what an awesome thing that was. I paid way too much money for a package deal that included Pushing Daisies, Judd Apatow, Chuck, and the Buffy the Vampire Slayer reunion. Even though I’m broke now, it was worth the price for just the Buffy thing alone (but all the events were great). For Buffy, they played the episode "Once More with Feeling" followed by a Q&A with cast and crew. Definitely a once in a lifetime event.
