I think the original poster of this video got their channel terminated. Sorry, and I hope they're doing well. I was unsure whether I should list this as 'for kids' since I love reading what other Lehrer fans have to say. Electric Company IS appropriate, of course. In case you're fumbling over whether or not you should hand your phone over to your kid with this blasting.
N Apostrophe T is by far my favorite song I've heard from Lehrer's time on Electric Company. Lehrer's writing is always charming, and I love how he never talks down to kids (EC was good at this in general, from the episodes I've seen).
