I don't have anything against fun things, but seeing the same memes we have all seen every day for years now is not really funny.

on one hand, I completely agree with you. on the other hand, i've had to make presentations and talks and the stuff just looks so dry and boring and people respond surprisingly well to old jokes. if you don't include any sort of lulz they just sit there thinking they're learning, but if you mix in a few memes, it helps wake them up and they start to pay attention.

I think a p-hash[1] would work better at detecting the same image... but what about a neural net that detects fun? That would probably be pretty enjoyable to write.
