Xtra Normal

Xtra Normal is a website where you can type up a script and the site animates it for you. Robotic voices read your text, and you can make the animated puppets change expressions, face the camera, point, etc. There are a variety of possible camera angles (1 shot, 2 shots, close-ups), a handful of soundtrack and noise options, and different backgrounds.

You can share it on their site, or upload it to YouTube when you're done. The site is still in beta, and it's free. You get what you pay for, but it's a lot of fun.

I scrounged together a super-cheesy, quick example (TOTI exclusive!):
