Exclusive news from Entertainment Weekly’s Michael Ausiello!

Remember that giant scoop I told you (via Twitter) I had gotten at the Golden Globes? This is it: Neil Patrick Harris is nearing a deal to appear in the May sweeps Glee episode that’s being helmed by his Dr. Horrible’s Sing-Along Blog director, Joss Whedon.

In retrospect, maybe I should’ve called this particular scoop “ginormous.” I think it’s warranted, don’t you?

Anyway, Harris wants to do it, and Glee creator Ryan Murphy sure as hell wants him to — he’s creating a role especially for the How I Met Your Mother scene-stealer. And yes, the part includes a little song-’n’-dance. In fact, the gig not only would reunite Harris with Whedon, it’d also reteam him with Zachary Woodlee, who choreographed the musical number in HIMYM’s recent 100th episode.

The one possible snag — and there’s always one, isn’t there? CBS has to OK its MVP’s appearance on Fox’s breakout hit. But at least since HIMYM and Glee are both produced by 20th Century Fox, there’s no conflict on their end.

So what do you think? Stoked, or stoked beyond belief? Try to describe your level of anticipation below. I know I can’t describe mine. At least not adequately.
