Reports are that Neil Patrick Harris has narrowed in on a deal for appearing in a May sweeps episode of Glee being directed by Joss Whedon, his director from Dr. Horrible’s Sing-Along Blog.

Harris reportedly does want to be on the show and Ryan Murphy, creator of Glee, definitely wants him. A role is being created especially for the scene stealer of How I Met Your Mother. The role does include some song and dance. The gig, in fact, would reunited Harris with Zachary Woodlee, choreographer for the musical number for the recent 100th episode of How I Met Your Mother, as well as with Whedon.

One potential snag- there always seems to have to be one- is CBS will need to approve the appearance of their MVP on the breakout FOX hit. However Glee and How I Met Your Mother are both 20th Century Fox produced, so on their end there is no conflict.
