Anvilicious: Comes with being a political punk musician.
Archive Panic: He's been responsible for quite a lot of music in his thirty-five-plus-year career. If you want to go through all his spoken-word pieces too, or the recordings where he's guested on one or two tracks, good luck.
Crosses the Line Twice: A favourite technique of his. "Will the Fetus Be Aborted?" is one excellent example of this: turning a traditional country song into an aversion of Good Girls Avoid Abortion. "Caped Crusader" is another example; he took statements from 9/11 mastermind Mohammed Atta and Attorney General John Ashcroft and spliced them into his song, inviting listeners to "spot the difference".
Epic Riff: Quite a few. One of the best examples may be "Caped Crusader". "Full Metal Jackoff" is another good example, but it'd pretty much have to be given the song's length.
Most fans are likely to take the line "Join the new Boston Tea Party" from "Dawn of the Locusts" this way given the American political movement that started up about five years after the song was released.
The main effect of hearing Jello's skewering of Arnold Schwarzenegger ten years down the road is actually nostalgia for the days when someone like Schwarzenegger could be considered an electable presidential candidate within the Republican Party. Mixed with Hilarious in Hindsight since Jerry Brown, the song's original target, once again became governor of California (ultimately leaving office in 2019).
A historical case of Dramatic Irony in that Schwarzenegger emerged as a harsh critic of Bush 43's Republican successor, Donald Trump.
Squick: The Intended Audience Reaction in "The Lighter Side of Global Terrorism", whose main point is how utterly creepy some of the screening procedures to which people are being subjected in the wake of 9/11 are.
