YouTube has been blocked in Thailand. Last year, the great 2Bangkok website played an April Fool's joke by replacing their homepage with a "Blocked by the Ministry of Information and Culture" page. Unfortunately, though, this time it's not an April Fool's joke.
I learned of this through the aptly named Thailand Jumped the Shark blog. For more info, please check out the post entitled Financial Times: Thai Government Blocked YouTube Over Lese Majeste Video
Personally speaking, this comes at a bad time for me -- just days after posting my first ever video on this website, and growing some ideas that I will do more. I guess I will have to find a different host than YouTube...
For more information, see the Nation newspaper's article: YouTube blocked because of clip 'offensive to monarchy'

So ah... What is the title of the video you posted? At least us on the outside could watch it... ;-)
Oh... it was the one on this website about teaching Thai students how to sing "Row, Row, Row Your Boat". Check out http://www.sgtowns.com/journal/002668.html
