Maybe I'm behind the times on this one. I don't know ...
Wasting some time on YouTube today, I ran across this video:
Hysterical! So I checked out the website, and found a number of other hysterical videos.
What I like about "How It Should Have Ended" is threefold: 1) The website is very slick and professional, 2) The animation is very well-done and easy to view, and 3) The videos are very thoughtfully scripted and rely on actual satire and parody for laughs.
I recommend the Blair Witch, Se7en, and It's a Wonderful Life videos.
