I don’t think that disagrees with my point. I simply think jokes are funnier the harder you work to get them. I too didn’t get it until seeing the arrow and label, but I would have found more enjoyment from a longer buildup and mental work to understand the joke than just having it served to me. Maybe I should add this context:
‘Explaining a joke is like dissecting a frog. You understand how it works, but the frog dies.”
