My humor mostly thrives off of a few select things, such as:
Taking a normal thing that's either relatively funny or completely normal, and re-enacting it in a really absurd or exaggerated way.
Writing really ridiculous or ridiculously bad songs (I have a band called Phukelum6atron that makes purposely bad music).
Randomness.
Inside jokes.
Either really amazing or really bad timing of words.
Being freakishly irritating to specific people because their reaction is funny.
Making fun of things that are either really absurd or really cheesy.
Making fun of music that is really awful.
Really nerdy things, like video game-related jokes that nobody gets..... that's why the Angry Video Game Nerd is my favorite YouTuber.
Cynical, sarcastic, or angry humor, which is why ADoseOfBuckley is my 2nd favorite YouTuber. I don't make this type of joke all that often because it doesn't really come to me naturally, but I do think it's freaking hilarious.
Jokes that pertain to music. This is similar to jokes that pertain to video games, because nobody gets them.
Oh, and I freaking LOVE puns. And by puns, I mean the most miserably terrible you can imagine. You would not believe the amount of carbon dioxide I've exhaled because me or a friend made a really, really stupid (and I mean EXTREMELY stupid) pun.
As for what I do NOT think is funny......
Jokes that poke fun at religion just because they can, and aren't even witty. If it's witty or funny, I'll laugh at it because I'm not easily offended. But some are just really stupid and are only made with the intent of offending people.
Jokes that are overly morbid, or go WAY to far. I mean, some jokes are okay if they go a little too far, but some people.... goodness, I swear some people are just plain sick. And when I see people laugh at that kind of thing, I start to question my opinion on them.
Jokes that are overly sexual just for the sake of being sexual. Like I said, if it's witty, I'll laugh. If you're making a sex joke that only evokes a laugh because it's really awkward or graphic and not even witty, then it's not funny. That's not genuine laughter, it's just shock laughter. And that's sad, because so many stand-up comedians get their entire career off of these "jokes" that aren't actually funny, just shocking.
