I do not believe it was a joke. I believe it happened. There is nothing funny about it, so I don't see how anyone would think others might be amused by a story in which they assaulted a young girl. Nobody has ever explained what could make someone think that would be funny.
I do not recall any apology from him at all. What he did was start saying, "well, she was ugly" and "Well she was an old hag" and changing her into a grotesque creature and telling us we should stop bothering him about having assaulted her.
Again, I apologize for nastiness unrelated to this matter and will make a concerted effort to improve upon that.
There's nothing left for me to say! In an effort to be less nasty, I give you the last word.
