I use the construction “Chekhov’s whatever” all the time to signify “something has been introduced so it will come up again later.” It’s a meme now. It has outgrown the gun.

You remind me of God in this classic:

A holocaust survivor dies of old age and goes to heaven. When he gets there, he meets God and tells him a holocaust joke.

God says, “That’s not funny.”

And the man says, “I guess you had to be there.”

Aw, come on.

“Cartoonist found dead in home. Details are sketchy.”

“Where’s the best place to hide after committing murder? Behind a badge.”

“Did you know today is the anniversary of the Jonestown massacre? I’d tell you a joke about it, but the punch line is too long.”

Yeah, robots looking at photos of kids that their parents voluntarily posted on the internet is no laughing matter. Way more serious than, say, violent crime. And nobody makes jokes about that, do they?

While I personally wouldn’t want AI inserting trains into photos of my kids without my consent, many kids like trains, and they could add some whimsy to an otherwise uninteresting picture.

I predict a sex scene. And a death scene.
