These next entries earn their place on the list for the sheer lack of thought the bands later admitted they gave to their names. If the bands had spent any less time coming up with something, they would have ended up calling themselves The Band Name.
22. Stone Temple Pilots
The story: One of the band members thought the logo on the STP car treatment spray bottles was cool. So yes, in case you were wondering: a lot of thought went into this.
Why it's ridiculous: Most of the band members seemed to think titling songs "Kitchenware & Candy Bars" and getting addicted to heroin was a fantastic idea, too. Evidence suggests they might not be the guys to turn to for well-reasoned decisions. The mental image of four guys flying around ancient Aztec temples matches up better with a psychedelic rock band, not a bunch of cock-rockers penning songs like "Meatplow" and "Sex-Type Thing."
21. Matchbox 20
The story: Explanations range from the name being the title of a song from an earlier band to the band's drummer seeing the word "matchbox" and the number 20 on a guy's shirt in a restaurant. Either way, shut the fuck up, Rob Thomas.
Why it's ridiculous: If you're going to pick a band name that doesn't mean shit, there's an unspoken rule it should at least sound cool (Soundgarden, etc). Matchbox 20 manages a triple play of mediocrity: It's incomprehensible, it's boring and it's not even very original, given how many other generic bands showed up at the same time as matchbox with "word-number" combos (Blink-182, Sum 41, 13 Engines, Seven Mary Three, etc.).
20. Smashing Pumpkins
The story: More of a cautionary tale than anything else, bandmates Billy Corgan and co. reportedly dashed the name off quickly so they could get on with their lives, not realizing they'd be fielding lame pumpkin-based jokes about it for the rest of their lives.
Why it's ridiculous: According to a November 1993 Washington Post interview with bass player D'arcy Wretzky, even the band thinks Smashing Pumpkins "is a stupid name, a dumb bad joke and a bad idea," which should tell you something. These days, they claim the name doesn't even have anything to do with pummeling squash fruit, in that "smashing" was meant to imply "great" (as in the British slang), like that somehow makes it less stupid. It'd be like accidentally crapping yourself on a bus, then telling everyone it's okay, because you meant to: Nobody cares why you did it, Shitty Pants.
19. Def Leppard
The story: Singer Joe Elliott thought of the name Deaf Leopard while he was in school (presumably while failing something). The spelling was later changed so the band didn't become confused with punk bands (who are known for their flawless spelling).
Why it's ridiculous: Putting aside '80s metal bands' fascination with animals for a minute (White Tiger, Whitesnake, Great White, Jackyl, Ratt) unless you're a Mozart-level talent, there's simply no excuse for including a word in your band's name that means you can't hear sounds. You might as well just call yourself Terrible Music and save people the energy of mocking you.
