Simon,
I can only hope that your and calamityjane's children (if she has any) aren't being taught your brand of "humor" when it comes to other people's looks. I also hope that they won't suffer the brunt of having their looks made fun of as you two have done here. You may think it's funny but it ain't. It's pathetic and sad and you ought to be ashamed.
So... let me get this straight: "F**k" = bad.
Saying someone looks like a horse (because you don't like them or their family) = good / funny.
Whatever.
