Both Data and Wesley Crusher fell victim to several practical jokes while at Starfleet Academy. ()

While Vulcans were not unable to understand the concept of jokes, they found them unnecessary and difficult to comprehend. During their encounter with the Dream Aliens, the  crew all suffered from nightmares. When B'Elanna Torres, Tom Paris, Harry Kim, and Neelix recounted theirs, they wondered what the nearby Vulcan Tuvok's dream was. Neelix suggested elements of a Vulcan nightmare might include being stranded on a planet in which the only form of communication is laughter. During most of Voyagers journey, Neelix made it his goal to make Tuvok laugh. (; et. al) In 2374, when Voyager briefly harbored , a Ramuran who was seeking asylum, Commander Chakotay spoke with Tuvok in his role as Voyagers chief of security, stating that Captain Janeway was looking for Kellin to contribute in some way. He noted that Kellin had been a security operative for her people, trained in weaponry, surveillance and fighting skills, and asked Tuvok where he thought she might fit in. Tuvok suggested that Neelix could use an assistant in the mess hall and at this Chakotay stated that he had just made a joke, telling him not to deny that he had just tried to be funny. Tuvok did not outright deny it, saying that it was Chakotay's decision to interpret his remark as humorous, but that the qualities Neelix described would help to defend Neelix against the periodic wrath of the crew.

Jokes which contained sexual innuendo were said to be "dirty". One of the expectations Lewis Zimmerman foresaw for his upcoming Long-term Medical Holographic program was the ability to swap dirty jokes with patients. ()

In 2376, after her failed modifications to the computer core of Voyager resulted in a number of malfunctions, Seven of Nine commented to Commander Chakotay that "Clearly, Voyager is not yet ready for assimilation." When the comment failed to amuse Chakotay, she explained that it was a joke and that The Doctor had suggested that she diffuse tense situations with humor. ()

La Forge didn't find the joke funny, as it was too old and Data "didn't tell it very well". Data however mispronounced the phrase "including the kidneys" after the joke was told, eliciting a laugh from La Forge. ()
