SF Chronicle:

Nearly four years after the launch of YouTube, it's startling just how much viral videos have come to resemble a highlight reel (or a gag reel) of recent history.

In 2008, the election was constantly reflected on video-sharing sites — and sometimes even influenced by such clips. But the year in viral video was not all politics; there was still plenty of room for a litter of puppies, brawling late-night hosts and a lion with an excellent memory.

Here are the year's top 10 Web videos:

1. Tina Fey As Sarah Palin

2. The Real Palin

3. Christian the Lion

4. "Yes We Can"

5. "Dr. Horrible's Sing-Along Blog"

6. Paris Hilton Responds to McCain Ad

7. Sarah Silverman and Matt Damon

8. Puppy Cam

9. Frozen Grand Central

10. Late-night Hosts Brawl

I know that with the exception of the Dr. Horrible vids, I've seen all of these. What were the most memorable videos that you saw this year? Which of our C&L vids did you send out to family and friends?
