Having received a Priority One distress call from an outlying space station, the Enterprise arrives to find they have been summoned there by a Federation commissioner merely to protect a shipment of seeds meant to sow wheat on Sherman's planet. The planet is also coveted by the Klingons, who are taking shore leave at the station. The trouble arises with tribbles - small furry creatures that seem to multiply without end. However, their fortuitous presence reveals both a problem with the wheat and a traitor on the space station. Written by

In the final scene Kirk is inquiring as to what has become of the Tribbles and is alarmed to think that Scottie may have beamed them into space to which Scottie, appalled by that assumption, answers, "Captain Kirk, that would be inhuman!" But with it being well known at this point that Klingons HATE Tribbles - and vice-versa, it should be obvious to all that the Klingons would destroy all of the Tribbles as quickly as possible. So beaming them into space may well have been the more humane thing to do. See more
How close will we come to the nearest Klingon outpost if we continue on our present course?
Ah, one parsec, sir. Close enough to smell them.
That is illogical, Ensign. Odors cannot travel through the vacuum of space.
I was making a little joke, sir.
Extremely little, Ensign.
