Rude, but sometimes humorous

I have a family member that doesn't give any thought to what comes out of her mouth. Some of things she says are rude and offensive. Recently she told another relative's mother that she looked like Joan Rivers! I can't help but laugh. For years now I have known of a female impersonator that strongly resembles this member of my family. I'm not the only one who has stated this. Some of my friends have agreed with me. Without further adieu....
