Writing with humor

I admire levity in writing just as much as I admire writing that is lachrymose. With that said, it can be hard to write funny, to keep the writing flowing, to still be masterful at language and land a punchline too. Not everyone can do it. I've put a few witty lines into more serious prose and people laughed, but I can't say that I've ever written an entire piece that was meant to be humorous. I tried last year and it was...okay. Definitely something I need to practice. I think I have a good sense of humor but when I wrote the essay I think I was trying too hard. Is it like stand-up comedy, where not everyone can do it but many people try? Or is funny writing something I too can nail if I just keep working at it? There's probably a happy medium in there where I'm not David Sedaris but I can get a piece published by McSweeney's (a goal of mine).

Who are some of your favorite authors who make you laugh on the page?
