to the TOS episode The Naked Time.
I say lazy ‘cause really, why would a spin off show choose to do a homage to its predecessor in the second episode!? A lame attempt at validation?
But then I watched The Naked Time so long ago all I remember of it was the famous shirtless Sulu scene. :’)
Tsk tsk, my friend. Must I continue to educate you? :P
This episode - as well as a handful of others throughout TNG’s run - where all originally written for “Star Trek: Phase 2” - the would-be continuation of TOS with Kirk, Illia, Xon (new Vulcan), Scotty, Uhura, Sulu and Chekov. That series was the original plan, to be launched in 1977 as the flagship series of a new 4th broadcast network here in the US. If that sounds a bit familiar it’s because Voyager ended up being the flagship of a 5th broadcast network in 1995.
They re-wrote them, but basically, “The Naked Now” and “The Child” and “Devil’s Due” and one or two other episodes where actually written 10+ years earlier for Kirk & Company to do. ;)
