Well, that may be an old email forward that's been around for years, but I've never seen it before and I find it humorous.
Why do some people automatically assume that just because they've seen something before, it's no longer worthy of someone else's attention? A joke isn't "old" if it's new to you.
Or could it be that the thread originator's past history here makes some people see anything he posts in a negative light instead of giving it a fair reading?
