These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Big Lipped Alligator Moment: The CD version of The Real Thing has as the final track "Edge of the World", a creepy lounge-jazz track about a pedophile (there's a mention of being "40 years older") who's offering "candy" to a girl. For bonus whiplash, it comes on the heels of the heavy Mideastern-influenced instrumental "Woodpecker from Mars" (the final track on the vinyl version) and a blistering note-for-note cover of Black Sabbath's "War Pigs".
Ear Worm: BE AGGRESSIVE! B-E AGGRESSIVE! B-E-A-G-G-R-E-S-S-I-V-E!
Epic Riff: "Epic" (what else?). Also the drum intro to "Midlife Crisis" and the keyboards in "From Out of Nowhere".
The main riff from "Smaller and Smaller" qualifies as well.
Face of the Band: To most, Faith No More is Mike Patton and a bunch of nameless guys. However, James Martin and Roddy Bottum also get a fair bit of recognition, Martin getting a cameo in Bill and Ted's Bogus Journey and Bottum being recognised for his work with Imperial Teen (and for being one of the few openly gay people in metal). Chuck Mosley is quite well-known as well, if only because Patton replaced him. Courtney Love is possibly the most famous person to ever be a member of Faith No More (much more than Mike Patton), but her stint with the band is barely known. Finally, while certainly the least obvious to the average listener, bassists and drummers tend to hold Billy Gould and Mike Bordin in high regard.
Mr. Bungle has a similar case. Most people familiar with the band can only name Mike Patton, but there are a couple of other relatively well-known members in the band, such as Trey Spruance and Trevor Dunn.
Mostly averted with Fantomas, though. Out of Mike Patton, Trevor Dunn, Buzz Osbourne and Dave Lombardo, the only one that isn't all that well-known is Trevor Dunn (being in a band with Mike Patton, Melvins' frontman and Slayer's drummer will do that to you).
It's just not the fandoms, either. Mike Patton and Anthony Kiedis really don't like each other.
In fact, the music video for "Epic" is largely a parody of the Peppers.
After a first meeting where they managed to at least settle the feud somewhat, Mike got angry at RHCP again because they asked the record company to postpone Mr. Bungle's California album until after RHCP put out Californication, so in a concert he sang a verse mocking "Under the Bridge" and pretended to shoot up. Kiedis then got Mr. Bungle thrown off a festival bill they were supposed to share with RHCP. Read up for more information - notably, the management and the other RHCP members emphasized to Mike that Anthony alone was responsible for that.
Hilarious in Hindsight: In the film "Bill & Ted's Bogus Journey," 'classic lineup' guitarist Jim Martin was introduced in the future as the leader of the "Faith No More Spiritual and Theological Center". The band's reputation only grew after their break-up and reunion, so describing a New Age facility named after them may not be too far off.
Opening their first (official) reappearance with a cover of Peaches & Herb's Reunited, no less.
Seinfeld Is Unfunny: Roddy Bottum's coming out as gay in 1993. He's been one of the most prominent LGBT faces in rock for long enough that people seem to forget that he was one of the first, (if not the first) rock musicians to come out (at a time when the world as a whole was still distinctly more homophobic than it is now) and paved the way for numerous other musicians to come out (Rob Halford even mentioned that Bottum was the catalyst for his coming out). To younger fans who either weren't alive at that time or were too young to be cognizant of it when it happened, however, it may seem as if it's a case of "much ado about nothing".
Signature Song: "Epic" or "Midlife Crisis" for the Mike Patton era, "We Care A Lot" for Chuck Mosley.
