Gah, I didn't remember that Java programmers have no sense of humor.
Sometimes our jokes aren't as funny as we think they will be. :(
Jokes that many members could come up with have no place on Hacker News. That's the road to devolving into a community where everyone tries to out-joke each other and the actual insightful comments get buried under the jokes. Just grin at the thought and enjoy the happiness, but don't post it. It's not that it's not funny; it's just that it is too easy a comment.
