Not against the rules, but there are a good number of people on HN who will downvote a humorous comment because:
1. They don't get it.
2. They consider it off-topic.
3. They missed the whole era when the internet was fun and interesting.
4. They mistakenly believe that it's against HN rules.
5. They fret about people in different cultures not understanding one another's jokes, so they try to vote the jokes into oblivion, rather than understanding that being exposed to the humor of other cultures is one way to learn about other cultures.
6. They're just grumps who find no joy in anything, and nobody else is allowed to enjoy things. See also: "Stop liking things I don't like!"
As for your comment being downvoted, it's considered bad form to comment on downvoting, so yours is doing down, as is mine. But I just don't care.
