Glad to see Crockford making jokes there. Unfortunately after leaving a comment on a recent picture update on his Google+ profile (in good humor), he banned me from his circles, unshared everything with me, and removed the comment. I still look up to him though.
Perhaps, but there is a key difference. The above example was said to a particular person about a particular thing (which I infer by the fact it was posted on a picture). The "evil" clause is a joke thrown out into the wild, directed at no one in particular. In other words, the above example is personal, the "evil" clause is not.
