Ken Sekine used to be a nameless stand-up comic. Then he turned to cyberspace and changed his stage name to Megwin and in the process became a premier entertainer in Japan, with more than 448,000 fans and counting.

Sekine now makes a living by posting homemade videos on YouTube. Since uploading his first video in 2004, he has continued nonstop for the past 10 years, never missing a day.

Megwin's videos feature comedic "challenges" that others are unlikely to try, including building homemade bungee equipment for jumping off his apartment building and eating cooked rice topped with a giant raw ostrich egg.
