We've come a long way. All of these kids nowadays are obsessed with their Harlem Shakes and their plankings and their Korean pop stars. Remember when YouTube was a much simpler time? Back when fads didn't get retired after 2 months and Rebecca Black wasn't a household name? If you were unfortunate enough to not be around in the early days of the biggest Internet video-hosting site in the world, then strap in, because you're in for a treat. Here are some of the most important videos from the early days of YouTube.

The First YouTube Video The truly captivating saga of a boy and his local zoo's elephants. Greatest video ever? Absolutely not. But it's important to remember your roots.

Evolution of Dance Was at one point the most viewed video on YouTube. We can't wait for a more modern follow up in which he's forced to twerk.

Numa Numa Guy A Moldovan pop hit and a socially awkward, yet incredibly animated chubby man. He had the viral video formula down pat before the term was even coined.

Star Wars Kid The original viral video. This clip actually predates YouTube, and had almost a billion views before being uploaded to the video site that we all know and love.

Chocolate Rain Singer Tay Zonday really paved the way for original song creators to market themselves on YouTube. His...unique song "Chocolate Rain" went viral thanks to his deep voice and breathing technique.

Back Dorm Boys The original lip dub video. Two college-aged Chinese boys singing along to a Backstreet Boys song proved to be a winning combination in YouTube's early days.

I Like Turtles The randomness of this zombie-faced turtle lover taught early YouTubers two things. First, news reports gone wrong are viral video gold. Secondly, children are here to be laughed at.

Grape Stomp Lady Again, news reports gone wrong are instant classics. Also, adults are here to be laughed at too. Most of the popular early viral videos became viral because it was easy to make fun of their subjects.

Leeeeeerrrooyyyyy Jenkins! Before there were let's plays, YouTube video game reviews, or just a general appreciation for nerd culture, there was Leeroy Jenkins. This brief and staged event parodied the seriousness of some World of Warcraft gamers; something massively appealing to the users that populated YouTube in 2006.
