Neil Patrick Harris inches closer to 'Glee.' Sing-off time!

Neil Patrick Harris is one step closer to getting his Glee on. CBS, home of Harris’ regular gig How I Met Your Mother, has signed off on a deal that would have Harris guest starring on the Fox series, Ausiello confirms. While nothing has officially been announced yet, it seems inevitable. Back in January, Ausiello reported that Harris and Glee creator Ryan Murphy both wanted to make it happen. With Joss Whedon, who directed Harris in the web musical Dr. Horrible’s Sing-Along Blog, helming an episode, it seems like all the stars have aligned for a reunion.

So as Harris’ guest spot inches closer to becoming a reality, I can’t help thinking about what character he should play. The guest spot is said to include some singing and dancing. The first idea that sprang to mind: Broadway vet sing-off! I’d love to see Harris as a rival to a truly worthy opponent: Matthew Morrison’s Will Schuester. Morrison deserves more than just showing the kids how to white-boy rap. One of my favorite moments of the series so far was when Morrison was matched up with another Broadway vet, Kristin Chenoweth. But their sweet duet was far too brief. How great would it be to see Harris as a blast from Will’s Glee Club past? They can play out their old high school rivalry through a West Side Story-like song and dance number.

What do you think of a Harris vs. Morrison match-up? Is there someone else you’d like Harris to play? Perhaps someone more Horrible? Or do you think he should teach the Glee clubbers about his awesomeness by just playing himself?
