I should take more advantage of YouTube

Not least because on it I can find videos such as "How to deflect a killer asteroid", an interview with Neil DeGrasse Tyson. (I admire him so. He's a scientist, an author, the director of a major public resource; he's articulate, he's funny, he has a gorgeous voice, he's really hot...)

Also from YouTube, via hitchhiker and kshandra: Amusing Muppet Bloopers! At which I laughed quite immoderately.
