i once organized a parent meeting at the school i worked at that made a lot of people very angry apparently , orphans do n't have a sense of humor .
You need to be pretty careful when you're joking about orphans.
I'm only 90% joking when I argue about them. They are all dumb
Making jokes about people who have lost their parents isn't something that most people would find funny. You should most likely keep those sorts of jokes to yourself, especially when they're demeaning a group as if they're lesser just because they had extremely bad luck in life. Showing some compassion could really make their day and they could view you as a hero, which is a lot better than being seen as a bully.
