• This kind of viral activity is only possible when there is repeat viewing. That means there's something about these videos that make people want to watch again and again.
• They have a sense whimsy. "All of these are 'feel good' spots that are fun and don't take themselves too seriously," he notes. They provide an escape.
• They all contain the bit of "how'd they do that?" and "is it real?" that many successful viral videos seem to employ.
• And finally, he notes, "Most of these have a deep musical connection, which definitely contributes positive associations. Just look at Apple's iPod ads for this."

Some viewers have blasted it for not being original. They say it is a rip-off from a scene in the 1997 Oscar-winning movie, “Good Will Hunting”.

Indeed, the commercial’s director, Malaysia’s Yasmin Ahmad, admits she had drawn inspiration from that movie directed by Gus Van Sant, though the idea also came from her own life. 廣告片導演Yasmin Ahmad承認她有受到心靈捕手導演Gus Van Sant的影響，雖然這個點子也是來自她的自身生活。

In the Hollywood movie, a man played by actor Robin Williams reminisces about his dead wife and her farting habit. 影片中，威廉羅賓斯回憶過世的太太和她的放屁毛病。

Her expulsion of gases once woke herself up from her sleep and, turning to him, she asked if that came from him. He admitted to it because he did not have the heart to tell her the truth.
有一次她太太放屁太大聲，把自己從睡夢中吵醒，她轉身問先生：「是不是你放屁？」先生承認是，因為他不忍心告訴太太事實。

He then goes on to share that imperfections are the “good stuff” in a relationship, and that no one is perfect, it is just a matter of whether you are perfect for each other.
然後威廉羅賓斯後來跟人分享就是這些不完美是一段感情中的「好東西」，沒有人是完美的，重要的是你們彼此絕配。

• youtube 成立Carl's Jr.頻道，廣告的創意延續之前Paris Hilton Eating A Burger，邀請九個youtube明星講他們怎樣吃漢堡的故事，youtube的影片渲染力甚至超過電視的TVC。http://www.youtube.com/user/CarlsJr
• facebook 成立粉絲團，愛好者集中地。http://www.facebook.com/carlsjr?ref=mf
• twitter也有露出，但很不幸變成客訴中心。http://www.twitter.com/carlsjr
• Carl's Jr.官網則是走高質感路線，只有放電視TVC內容：http://www.carlsjr.com/

1. Create original content – Instead of trying to push existing assets online with banner ads and video buys, a smart company will reach out to prominent users and elicit their help with creating original content that will appeal to that user’s existing fanbase.
   利用youtube頻道的名人既有fans的基礎，藉由名人所拍的影片推銷給fans，加速傳播。
2. Involve the viewer – If online content is good, viewers will often want to emulate the campaign with creative of their own, so smart companies will encourage that response and find ways of compensating users that go above and beyond to engage with the brand by creating videos of their own. In this case, each sponsored video ended with a call out by the star to the viewers to encourage them to make their own ‘How do you eat yours?’ video. As a result, while most pure UGC campaigns require a huge prize or some other promise of fame and fortune to get a response, this campaign is fueled by viewers’ desire to relate to the personality behind the video, and the compensation is the fact that the star might actually see the video response. A UGC video response campaign also doesn’t have to cost a lot when using YouTube, since the site’s built-in video response feature and viral sharing tools mean the backend is already in place for a campaign with little to no effort required from the sponsor company.
   讓觀賞者參與，由於網路名人個性容易引起模仿，加上輔以影片ending問所有觀眾「how do you eat yours?」期望引起迴響。有別於一般名利誘因，此campaign花小錢就可以擁有消費者自製的內容(user generated content)。這些消費者自製的影片內容，被列入youtube Carl's Jr.頻道中的「我的最愛」，目前看到有20支。
3. Give creative freedom – Too often, companies get online stars involved in their campaigns and then limit what they can say and do, or try too hard to keep them on brand...By giving the content creators more creative control, the videos will be more original and more unique, the views will be higher, and the costs associated with trying to control the message will be much, much lower.
   給予創意的自由，影片的內容會更原汁、更獨特，也就有更多人看。
