So weird. I just got a copy of ten episodes of this show on DVD. Some dude sells them on eBay. Worth every penny. I can NOT stop collecting educational films. And you're dead right regarding the feeling they give you. As Joel from MST3K once put it in an interview on NPR: "These old educational films just . . it's hard to explain . . . when you watch them it's like you're in someone's weird house and you just feel bad." I've never been able to explain it better. Nor why in the world I am prone to insatiably seek out that feeling by watching them.
