Yes, I vaguely remember a Dave in college who was a very funny guy at the time, although I did not know him well at all. Sometimes these people who were so funny are actually very angry about something, and if you could really analyze what they are saying, which I will admit that I did not, you might figure out that they are on a completely different planet and there is really no way to talk to them about that, even if we could understand what they are taking about, but of course we cannot.
