What has 3000 legs and 4 tits? A race for life. Get it?
I'm not sure I do actually. Why are you making fun of people with cancer?
I was making fun of the women who participated in this race, because they are insane to do something like that.
Breast cancer is a serious disease, and you shouldn't make fun of people who have gone through it. They deserve to be treated with respect, not ridiculed. Charity races like this can raise both money and awareness for breast cancer, and other issues, and can show people struggling with the disease that they aren't alone.
Shame on me. I am sorry.
I'm glad you're able to understand why what you said was distasteful, and I forgive you. I'm sure there are lots of other jokes you can tell that don't mock others.
