AFAIK you just gotta say something funny anywhere.
Okay I see this in the modlog and it makes me snort every time. Not the full comment but this bit given the context of what it relates to:
"No, I cannot help myself, punitive justice remains bullshit and it's disgusting how this board falls into it."
It's so absurd. I hear "No, i cannot help myself" in the same delivery as "a succulent Chinese meal" and like I had to type that out manually so I think it should be added because of my effort alone 
(to any power havers who can make it so)
that is a good one yeah, what a thread
Sadly I think it's pretty common for good taglines to fall between the cracks. There was one a while ago that never got added AFAIK. It went "Hexbears get sent into threads in pairs, holding only one keyboard. When the one with the keyboard gets banned their partner picks it up and keeps posting" but phrased much more fluently, making fun of the myth about Red Army soldiers.
I think I saw this one earlier today as a tagline
What a thread indeeeed lmao
I know right!! Hahahahaha that's a good one, we need comm or thread for submissions.
I love it when you are reading comments and there's just a reply or exchange that's so funny and you have to giggle irl.
~~I'd be all lets have c/bestofbear but that's so reddity~~ hehe..he
I meant it's a lovely idea!!!
Yey!!!
Reddit would never be this based.
Hexbear you've done it again!
Just post a reply saying "new tagline just dropped" and the mods figure it out from there.
When the lathe of mods arrive upon thy comment or post
Mandatory 
(I forgot that emoji)
There's so many I forgot!
for when I gave myself the "Operations Inspector" title.
