The headline says it all, really.  According to EW, Dr. Horrible himself, Neil Patrick Harris, is expected to join forces with Dr.H creator Joss Whedon for an upcoming episode of FOX’s hit show Glee.  In fact this would be quite a reunion for NPH; not only will he team with Whedon but he’ll also work with Zachary Woodlee who helped choreograph the song-and-dance inspired 100th episode of How I Met Your Mother.  NPH is expected to both sing and dance in the role, no surprise here.  The only road block is CBS allowing NPH to jump over to FOX for the shoot.  EW’s Ausiello points out that HIMYM and Glee are both produced by 20th Century Fox, so there really shouldn’t be an issue.  Glee returns with all new episodes April 13 on FOX.
