Well, yeah, I wouldn't take anyone who used that phrase seriously. I found it more annoying than funny, mainly because I hate that phrase and find it incredibly disrespectful. Personally, I think being called a whore would be less degrading than being called a Nazi.
You should try chemistry jokes. Those are much funnier.
So what if it's been said before on the Internet. I haven't heard it before, and I never thought to look for it before reading it here. That doesn't make it any less funny. So, I do mean to spoil your spoiling of other people's spoiled fun.
