I don't believe you deserve the downvotes you're getting. Sometimes a good joke is so good that it appears shallow at first glance, but only upon reflection does the true humor show through. A shallow callout such as yours is sometimes necessary to call the reader back to it for that further reflection.

A few thoughts on this:

- it’s against HN guidelines to comment on downvotes

- comments are supposed to be substantive, further the discussion, and inspire curiosity (and I think the joke failed at all of those)

- it’s not a great joke, just a shallow pun

I’m guilty of often downvoting jokes on HN that are just jokes with no substance, partly because they end up causing confusion and noise, and they make the discussion less interesting. Reddit is a great place for those.
