I’m a big always sunny fan too. I think they made fun of stuttering once in a previous episode, I believe it was “the gang gets quarantined” but I’m not sure about that. The way I see it, if I’m gonna laugh about every other offensive joke they make on that show, I can’t get mad at them once it comes to my neck of the woods. But if anyone feels differently about it that is obviously valid tho. That’s just how I personally handle that scenario
