Urlesque counts down the top 100 viral videos in the history of the web.

#70 - Will It Blend?

Does viral marketing ever actually work? If it involves blending everything from iPhones to golf balls, then yes, it does. A viral campaign of infomercials, the Blendtec series hit it big when Blendtec founder Tom Dickson showed off the Total Blender's power by taking requests online and attempting to blend everything he could get his hands on. We're not sure how well the Total Blender sold, but the campaign has currently blended (blound?) over 85 items and garnered millions of views -- even spawning a popular interweb catch phrase: "WILL IT BLEND?" -LW

#69 - Samwell - 'What What (In The Butt)'

The video for a song by Sam Norman, better known as Samwell, was created by Brownmark Films and first put online in February 2007 and went viral for its weird staging and camp references to homosexuality. It was parodied in an South Park episode, which increased its popularity. (Probably NSFW) - RV

#68 - Wii Fit Girl

Unbeknownst to her at the time, Lauren Bernat became a viral sensation after her boyfriend posted a video of her, titled 'Why every guy should buy their girlfriend a WiiFit,' that showed Bernat playing a Wii Fit hula hoop game in her underwear. At first, she was furious at her man and forced him take down the video, but it was too late as (unsurprisingly) her gyrating hips took off like wildfire through the web. Millions of views later, she has since embraced her fame. Bernat got her revenge on her boyfriend on the Tyra show, and has even surfaced as a spokesgal for another Wii exercise game. - KR

#67 - Little Superstar

Sometimes things get popular on the internet simply because we just can't figure them out. That just might be the case with this clip named 'Little Superstar' that features a young boy (or small man?) breaking out some serious dance moves for his friends. According to various sources, the clip is actually taken from a "Kollywood" film called Adhisaya Piravi (Kollywood is Bollywood but in the Tamil language) and the little superstar is played by Thavakalai -- an adult actor who, because of the viral sucess of the clip, was soon featured on everything from Best Week Ever to MSNBC. Despite Thavakalai's mainstream success, the clip lives on in the YouTubes -- with over 12 million views and counting. -LW

#66 - Randy Pausch's Last Lecture

After Randy Pausch, a college professor at Carnegie Mellon University, was diagnosed with pancreatic cancer, he set out to do whatever he could to raise awareness about the horrible disease. On September 18, 2007, he took the stage with high spirits at the college to deliver his inspirational "last lecture" about acheiving childhood dreams. He lost his battle with cancer less than a year later, but thanks this web video, his message and legacy continues to inspire and impact millions of viewers everywhere. - KR
