They aired this on Halloween on my local NPR affiliate, and the second half was a very louche "Land Before Time" (the Conan Doyle book, not the Don Bluth movie) with the Star Trek cast, clearly after having had several drinks a piece. Wil Wheaton was shockingly funny.

Awesome, Jerry Hardin, aka the guy that played Mark Twain in those holodeck episodes.

I had this tape when I was a kid!

Doyle never wrote land before time. He wrote "the lost world" Edgar rice Burroughs then wrote "the land that time forgot". which I haven't read but I imagine is a lot more racist than 'the lost world'.
