speaking of "Puppet masters" wasnt that adapted into one of the old star trek episodes? And later made into a movie?

*** a half decent movie

Wasnt the "Trouble with tribbles" episode based on "the rolling stones"?(or was it "flatcats of mars")
*** TWT was based on a concept from The Rolling Stones juvenile novel

Door into summer (guy cryo freezes himself, right?) wasnt that also released as "time enough for love"? or am I confused?

*** DIS is where the guy freezes himself - I liked the cat best; Time Enough for Love was a title for a later Heinlein novel where Lazarus Long goes back in time to meet his mother & have sex with her. Just lovely.
