"The Naked Time" is the fourth episode of the first season of the American science fiction television series Star Trek. Written by John D. F. Black and directed by Marc Daniels, it first aired on September 29, 1966.
In the episode, a strange, intoxicating infection, which lowers the crew's inhibitions, spreads throughout the Enterprise. As the madness spreads, the entire ship is endangered.
This was the first episode in which the audience saw the Vulcan nerve pinch (the nerve pinch was actually filmed first in "The Enemy Within", but the latter was broadcast a week after "Naked Time").
The story has a sequel in Star Trek: The Next Generation, the 1987 episode "The Naked Now".
