This question has historical significance, but it is not considered a good, on-topic question for this site, just as said on locked questions. Does it deserve to be undeleted and locked for good?
Seriously though, historical locks are for questions that were on topic once, but became off topic due to a change in the site's scope. That's not the case here.
Also, undeleting the question would send the message that this kind of prank is acceptable. That's also not the case; the user (sock) who posted that question was deleted for spamming the site.
And all the chatter about avocados really needs to stop...
