Lafingwild is a spelling adaptation of the play "Laughing Wild" by Christopher Durang. As Daniel's favorite play, he chose to use it to derive his email address. "Lafingwild2". Now ya know..
An additional aspect of this, was this video which he directed me to watch several months ago, when I inquired about his email address. Much as anything that Daniel directs you to, you may find it funny as well as a bit disturbing.
