XKCD Isn't Funny - #1762 - Moving Boxes & #1763 - Catcalling
Is this even a joke? Like, it's funnier than a blank white square, but it's still less funny than actual formed comedy. Every box might as well just have been labeled "I'm quirky".
Not all jokes make sense broken down into a setup/punchline equation, but let's just go with this for a second.
Setup: Randy forgot to label his boxes when moving.
Okay, that's fine. It's not the most interesting setup, but not all setups have to be interesting. Maybe someone helping him move will unintentionally open his sex toy box instead of his blanket box.
Punchline: Randy labels the boxes with words that do not represent what is inside the boxes.
Like, what even is that? That's not funny! That's not a joke! If this was Questionable Content or whatever and it was just in the background, it'd be kinda cute as a character thing, but this is the entire comic, this is all we're given!
Literally everyone who has heard the word "catcalling" as thought of a variation on this joke.
Also, missed opportunity: Not having it turn out that the definition of 'catcalling' was somehow integral to the structure of the universe.
