One of the most popular questions on Stack Overflow, What's your best programming joke? has recently been deleted. Why was this done, rather than migrated to programmers.SE? Does this not fall into the broad purview of Programmery questions, or is it really off topic?
I'm somewhat neutral on this myself, as I usually oppose "fun" questions that are there simply for fun's sake, but this is a rather old SO question and historically other similar questions from SO's infancy have been tolerated with grandfather status. Can anyone make a strong argument for or against?
