Felicia Day is also the star of the online series The Guild. If you're not a geek like me, you may not love it as much as I do, but this blog isn't about what you covet, now is it?
Day portrays Codex, the only sane member of the MMO guild the Knights of Good. The other, crazier members of the guild are Vork, Bladezz, Clara, Tinkerballa, and Zaboo. They all have real names, except for Tinkerballa. Codex is Cyd and Clara is Clara. I only remember that because Codex is the main character, and Clara is Clara.
Through a series of unfortunate events, the members of the guild meet each other in real life, and wacky high-jinx ensue. It won't take very long for you to watch and find out what happens; each video is less than eight minutes long, and there are only four seasons so far.
The later ones include Wil Wheaton wearing a kilt.
You can buy The Guild on DVD, but since it's available online, you may as well watch it on Bing before you go spending money. It's not always safe for work, language-wise, and you really shouldn't be watching videos at work anyway.
Also, there are music videos.
