The Don Music clips actually have a bit of history -- parents complained to many PBS stations after their children, who had seen these segments, would bang their head on the table (or piano, during such lessons) when they made a mistake in imitation of the muppet version.

I find it funny that Don didn't know Kermit was even in his house.

Bill is like seven years old in every interview I've seen him in. I used to like some of the stuff he did in the earlier days, but it has just gone straight downhill. I clicked on the video expecting an actual slap, rather than figuratively. Because that's something I'd like to see.

The problem with making a science-favorable video explaining why evolution is is spiffy is the same problem with making a turtles-all-the-way-down-favorable video featuring such experts as Bill Q. Mortimer, Grandmaster Turtle-Philosophy Symposium, Professor Emeritus of the Pittsburg National Convention of Turtle Universology, and editor-in-chief of Infinite Turtles, the timeless and esteemed periodical of world turtle systemic deduction. There's no credibility if you've got degrees in the field you're arguing for, when the demographic for the video is people who think your degree is roughly equivalent to Elmo.
