Curb Your Enthusiasm...I give "trigger warnings" to people I suggest the show to but don't know really well. Because I enjoy getting people to smile and laugh, Im regarded as a genial fellow (sic) and inevitably the subject of comics and comedians and stuff like that comes up.
This is Texas, and a lot of people still don't know about Larry David and Curb. But that doesn't mean they won't like it. But I would not be a responsible adult if I just sent them into that world without letting them know, hey, I don't know you THAT well, and you may or may not appreciate this. It's funny as hell, BUT...
It's just common courtesy!
