Ze Frank is the healthiest thing I've discovered on the internet for a while (when you need to laugh), see related video on Slime Molds: https://www.youtube.com/watch?v=OltvGZUvpvw [edit- spelling]
That was the most information-dense Ze Frank vid I've ever seen. Very little of the trademark humour (except for bebbes) but very interesting indeed & seriously worth a watch.
Science hippies made an appearance, too.
