I Think One Of My Favorite DnD Things Is When Random Rolls Become Retroactive Lore/Quirks For The Character.

I think one of my favorite DnD Things is when random rolls become retroactive Lore/Quirks for the character. Not even as a DM ruling, I mean something the whole table adopts organically, whether seriously or as a running joke.

A paladin I DMd for failing every single perception roll turned into him canonically needing glasses and not realizing it.

A combination of failed perception checks and concentration saves becoming a character having ADHD and that getting worked into the acting.

My gnome barbarian with low intimidation rolls despite doing/saying some actually terrifying things suddenly having a voice that cracks like the "WHEN WILL YOU LEARN?! WHEN WILL YOU LEARN?! THAT YOUR ACTIONS!! HAVE CONSEQUENCES!!" kid when he shouts.

Or my favorite, my tabaxi artificer, Gus, comedically failing every religion check when it comes to praying so now it's a whole plot point that gods literally do not perceive him.

(Yes this is an invitation to reply or tell me in the tags if you've had any canon-altering rolls like this I love PC stories)
