Hello! is a concept for a television show developed by JHM and Jokerman215, retooled into the concept for a webcomic. It is a kind of double-layered "skitcom" revolving around a series of bizarre recurring characters getting themselves into awkward and surreal situations, intermingled with a series of even weirder, often unrelated sketches and fragmentary stories framed as appearing on the "main" characters' televisions or radios. Dances on the line between the whimsically absurd and deeply disturbed (or disturbing).
Ax Crazy: The Living Room Angel and Lorena. Harold, Tom's "quirky" roommate, appears to be this, though whether he is a Serial Killer (as everyone strongly suspects) is up for debate.
Eldritch Abomination: Cthulhu, the Living Room Angel, possibly whatever Bus Stop Girl is waiting for...
Epic Fail: Many of the characters' attempts to do anything result in much disaster. Mike's attempts at "totally original behaviour" are particularly ridiculous in execution.
Hell Is That Noise: In-universe, Mike's band records an album based off of old sheet music accidentally left in the Living Room Angel's cupboard. It's apparently very unpleasant to listen to.
Tom's "big voice." Represented by extreme distortions of font.
Hurricane of Puns: The "political parties" arc. How many jokes using the word "party" can one fit into a comic? Lots.
In Joke: Where else do you think half of these characters would come from?
In That Order: When Tom preaches his "gospel," the order in which one is killed or maimed by things from beyond the stars is a very important point of conversion.
Naughty Tentacles: The Japanese schoolgirls that regularly cling to Handsome Bill have these.
Neoclassical Punk Zydeco Rockabilly: Mike's band is generally described by fusing together the names of totally disparate musical genres (often ones which Mike ostensibly hates with a passion) followed by "but with" and some unusual instrument. Example: "We're like Romanian folk-punk meets Goa trance, but with more free-jazz oboe solos."
