Rachael has already met three of YouTube's most popular "stars" -- a guy who posted his cell phone number for millions to call, a bride who "wigged out" the day of her wedding and a cute pup who just couldn't stay awake. Now Rachael learns the stories behind three more of YouTube's most popular video sensations.

Emma Feeding Crowley Popcorn

Three-year-old Emma loves to use the phone, but there's still one concept that eludes her -- people on the other end can't see her! The video of Emma feeding the dog and trying to show it to her dad over the phone took on a life of its own once it was posted. "It crashed my e-mail," says Emma's mom Stephanie. "I got so many e-mails from people all across the world!" Rachael has a gift for the family that might solve their problem -- Tango video phones.

"Papa can't see you!"

Bruce Lee Painting

Over 1.1 million viewers have checked out Phil Hansen's innovative method of painting a portrait of Bruce Lee. Instead of brushes, Phil dips his hands in paint and then karate chops a wall-size canvas! He explains that there was some pain involved in the creation. "I did this over a couple of days," Phil says, "because there was no padding behind the wall, so my hands kept getting all bruised!" Check out more of Phil's artwork at PhilInTheCircle.com.

"Everybody was kung fu ... painting?"

Yogi the Pug

Yogi has become an Internet sensation due to one bizarre feature. His owner Kevin explains, "I adopted Yogi when he was three years old and his tongue was already out like that. The previous owners said that he might have had a stroke when he was younger. He can't pull it in, but he can use it." The pup has amassed such a huge fan base that Kevin started his own Web site to showcase his unique dog -- YogithePug.com.
