Stemming from the late 90's, this was derived from the know-it-all of your friend group or family that couldn't wait to share that Bob Saget was actually a dirty comic and not anything like his character on Full house. The issue is, we already knew this.
"Did you know that Bob Saget is actually a very dirty comic? It's so hard believe because he's such a nice guy in Full House"
"Susan, someone needs to call you out on your sagettry, everyone knows Bob Saget is a dirty comic."
"Wow that's crazy, did you know that tomatoes are actually a fruit?"
"Yeah, Tim. We know, we all know, we've known that since 3rd grade science class."
