So you know what's winning the internet right now? Dr. Horrible's Sing-Along Blog. It's quite good. It's got everything you'd want in a Sing-Along Blog, including: Neil Patrick Harris as an aspiring super-villain; ill-tempered horses; extended musical numbers; sporks; copious amounts of frozen yogurt; and much, much more.
It was available for free on the internet for a while, then taken down and sold exclusively on iTunes, and now is back up again. I don't know for how long the freeness will last, so maybe check it out sooner rather than later.
The conception and production of this were cool: creator of Buffy and some similar shows, who also moonlit as a writer for The Office last year, got bored during the writer's strike, and wrote, produced, and filmed this 42 minute film pretty much independently. You can read more about it on wikipedia's entry, but the guy in charge expressed pleasure at being able to free himself of the time- and creative-constraints of the studios.
In short, I like it. And it's my solemn duty as a blogger to link to free things that I like. (Note: The link to the hulu video is the second sentence.)
UPDATE: You know something's big when it's eliciting popular youtube response videos:
