Land of the Lost

I saw this and, well, the truth is that I know more about the tv show Land of the Lost than I probably should (eyes roll). 

For example, it was mostly written by some of the greatest sci-fi writers of that generation. 

But back to the picture. My  mega bonus trivia: members of UCLA's basketball team were inside the sleestack costumes. Including Bill Walton who said it was a hoot. Bill Lambier was in high school in LA and was sometimes there, too.
