Dream on.

That was likely the reaction most Glee fans had when they first heard that Neil Patrick Harris might guest star on this Fox hit.

He appears on How I Met Your Mother, they figured. No way this crossover would ever take place. But leave it to Ryan Murphy and his connections to make this dream casting a reality.

It takes place on next week's episode, aptly titled "Dream On." Get a look at Harris in the role of Will's former nemesis, Bryan Ryan, right now - and then check out the official promo for this monumental event below:

Glee Quotes

Relationships are a lot like flowers. If you find the right seed, put it in good soil, give it water and sunlight, bam. Perfect bud. And then comes winter and the flower dies. But if you tend that garden, spring will come along and that flower will bloom again.

Finn

I had sex with you because you got me drunk on wine coolers and I felt fat that day. But it was a mistake.

Quinn [to Puck]
