Anal Probe (TOS) -- The enterprise encounters a flying saucer. Kirk raises shields, but the aliens in the flying saucer are able to abduct a sleeping chekov through the shields. They install an anal probe in his butt, in order to gather data about the Enterprise. They then return Chekov to his quarters, and he remembers nothing of the experience. The alien ship then leaves.
When Chekov wakes up, he starts having humungous uncontrollable farts. Every time he farts, the Enterprise shakes violently. Dr. McCoy examines Chekov and determines that an anal probe is the cause of his uncontrollable farts. Dr. McCoy tries to remove the anal probe, but has no luck.
As Dr. McCoy continues to try to remove the anal probe, Scotty informs Kirk that if Chekov's farts do not stop, they will tear the Enterprise apart. Just as the situation seems hopeless, the flying saucer reappears. Once again Kirk raises shileds, but the aliens on the flying saucer are able to once again abduct Chekov, who is this time aware of the incident. The aliens remove the anal probe from Chekov's butt, and then return him to the Enterprise. The alien ship then leaves.
