Yeah, I do. Haven't in a while now, just started putting my time into some other stuff recently. I'll get around to doing it again, been having the itch again recently. I've always written stuff and kept little notes for bits and stuff, similar to you.
I'm not like a full time comic or anything, just stuff in and around my city. Get booked sometimes for a paid gig here and there, but not anywhere near being a working comic. Started it like...6ish years ago? It's pretty fun, I always suggest people to just try an open mic if they have any interest in it.
