Neil Patrick Harris and Joss Whedon Both Get Glee-ful

Back in October there were rumblings of Joss Whedon directing an episode of Glee. Now we are also hearing that Neil Patrick Harris is going to be starring in an upcoming episode of the hit show. As many of you know, Neil was the star of Joss Whedon's internet hit "Dr Horrible's Sing-a-Long Blog". What are the chances that the episode Whedon is to direct will star his former Doctor Horrible? It would definitely be a huge ratings boost for the show (not that they need it). As of yet this is just speculation on all our parts, but it would be fantastic if it turned out to be true. I guess we'll just have to stay TUNED to find out more.
