Part forum game, part critical think piece, part writing project: how would you resolve some of the classic Star Trek episodes by just changing one small thing?

For example, the entire plot of TOS 1x05 "The Enemy Within" could be solved like this:

Scotty: Sir, the transporter is malfunctioning.
Kirk: I can't have men trapped down there.
Spock: What about a shuttle?
Kirk: Yes, yes. Send a shuttle down to...
Spock: Retrieve the crew? At once.
