What's worse than a bee sting? Two bee stings. What's worse than two bee stings? The Holocaust. What's worse than the Holocaust? Three bee stings.
Are you making a joke about the Holocaust.
Yes, I think it's really funny.
Making jokes about the Holocaust is not ok because it makes light of a terrible period in history in which millions of people died. There are lots of really good documentaries that show the atrocities took place during that time. I think it would be good for you to watch some, so you'll have a better understanding about why those jokes are inappropriate.
