It's a fun one-shot :)
When you find that sweet spot between funny and serious... A character that is a single really bad joke but fleshed out so much that people don't realise the joke until several sessions in... Ooh, that's the good stuff.
I wish I could find it in me to enjoy running gag characters; but my issue is as soon as the bit runs fallow, so does my interest in the concept
You gotta live it. And make it progress. I also one time did Smokin Joe Rudeboy. If you do not know who that is, you are missing out. Try in in youtube and tell me this isn't an epic concept for a character.
Oh my god that's gold. Smokin' Joe is just a wild west coded Bard with a couple d8's of Fire damage to his Vicious Mockeries, I'm convinced
If I had time, I was going to get Continual flame rings on his middle finger. He was the king of Vicious mockery, Dissonant whispers, and used Healing Word to intimate dead people back to life NOW !
Also comes with his teamsong : https://www.youtube.com/watch?v=e0pELGUfj2Y
