The best viral videos of 2008

Among other things, 2008 will be remembered as the year that professionally produced Web video finally trumped amateurs with webcams. Although YouTube continued to attract a huge number of viral video viewers, the Internet celebrities of 2007 were overshadowed by real celebrities, as television segments enjoyed a legal (and almost profitable) life on the Internet, and professionally produced shorts popped up on smaller sites all over the Web. But despite Andy Samberg's best efforts, and Sarah Palin going viral like a case of the measles, people still couldn't get enough animal videos. We'll begin with one of our favorites, about a very special feline named Christian.
