I’ve had some early indications that there may be a generational divide over this cartoon — that many of those under, say, 30 may not understand the reference.
I’m not going to explain it.
I’m not going to link to a Wikipedia article that explains it.
I’m not going to invite people to explain it in the comments.
I’ve started blank-faced at enough memes and reaction GIFs over the past few years that I figure, maybe it’s someone else’s turn not to get the joke.
…Oh, fine.
