the writer's room discussion

like the person above said, real-life jokes or movies and shows sometimes have jokes or styles of jokes that you can use (ofc if it seems forced in the movie or whatever it would irl too)

It’s really hard for me because I myself am not a funny person, but try making ironic scenes and let your brain be creative, you could also try to talk eith a funny person and analyze what they say

Sometimes I have trouble picking up on humor or writing it, but what helps me is watching other comedians and learning how they deliver jokes. Also, sometimes when you read or watch a movie/tv show and laugh, start to think about what made you/others laugh or what makes it funny. Once you learn to pick up on humor from others and learn what makes someone laugh, you can start to recreate it.

i reaaaalllyyyy need to learn more of this!! i want to create funny characters for my stories but i’m not funny myself so 😭😭

Specificity and exaggeration can amp up a bland joke. Try painting a ridiculous picture in the reader's mind. For example, let's say a character has been waiting a long time:
"I've been waiting forever."
"I've been waiting for a million years."
"I've been here since the cretaceous period."
"I've been standing here since dinosaurs walked the earth."
"I've been here so long I grew legs and crawled out of the sea."

I agree with Lily that watching stand-up and comedies helps a lot. You can also read satirists such as Terry Pratchett, Mark Twain, Oscar Wilde or Paul Beatty.

i think look online for examples or read books that have lots of humor, i think witty dialogue often adds a good sense of humor

Writing humor is like writing anything else - it has to be organic to the character. You can't wedge jokes into dialogue for the sake of adding some "funny" to your text - humor, like drama like suspense, like violence has to be organic - if not, it comes off reading and sounding phony.
You may want to read Elmore Leonard and Carl Hiassen who are known for their offbeat humor and skill at injecting humor into dialogue. Also check out Janet Evanovich, Jana DeLeon and Sarah Strohmeyer who all "write funny" and the essays of Dave Barry and David Sedaris.
