Personal snarks: This encompasses all "cliches" and their associated "anti-cliches" that involve the characters themselves. Data's contractions (and people bringing them up), Janeway's coffee addiction, Chekov's accent, McCoy's Spock bashing, Kirk's pronounciation and skirt-chasing issues, etc. Hence a fivist can amplify and/or explain these traits for humorous effect.

For example, in my fivers I've turned Dax into a "slang-obsessed techno-freak," as I call her. That doesn't mean that I don't like Dax, 'cause I do, it's just that she presents the most easy conduit for jokes that involve slang and Treknology.

Along similar lines, I've pushed O'Brien's work overload (brought to my attention by Phil Farrand) into an out and out burden that the others deliberately put upon him. This also provides convenient opportunities for "easy" punchlines by having him win office pools on the station to give him time off, since as the "oldest" (I think Odo is technically older, but he's still relatively emotionally immature) crewmember he needs vacations and a full night's sleep more than the others, at least in my fivers. He'd also win these pools because after six years on the Enterprise and upteen years on other vessels during the Cardassian War, he's the one that's the most mature in many respects, both professionally and personally.

Equipment snarks: First off, as Derek says, the computer as a character is always funny. Along these lines, the transporter and the holodeck are rife with their own problems and provide ample fodder for jokes, especially in fivers. Similarly, I enjoy the sound effects joke first found in Bob and George, hence the use of Kablazmo and other such sounds. The Trek creators even provide for this kind of material, what with their inconsistent protrayal of the capabilities of the computers, shields, weapons, tricorders, etc.

Plot snarks: The fourth wall (or lack thereof) jokes. As much as we love Trek, there are ample examples of "idiot plots" and people forgetting the technology they have and what it can do. As Bashir says in one of my fivers: "Sounds rather convoluted-oh yeah, this is DS9. Never mind."
