There are apparently something in the neighborhood of 50-70 million videos on YouTube. I've been browsing it a fair bit lately, and finding good stuff, but I can't fathom what I'm missing simply by not knowing to look for it.
So I thought I'd share some videos I found and liked, and figured others might want to do the same. So to start off, I have one comic book related one, and one classic clip from my childhood.
The Lobo Paramilitary Christmas Special - The infamous fan film.
Sesame Street: Bert's Nephew Brad - I have no idea how long it's been since I last saw this, but it still seems familiar and funny. Modern 'Sesame Street' can't hold a candle to the old stuff.
Oh, and for everybody else who missed out on San Diego, there are plenty of videos from there. Entire panel discussions, even. Including this.
