Photobombing is when an unexpected subject appears in a photo, often in the background and usually with humorous or disruptive effect.
ChatGPT understands photobombing, so start by using that term to explain that’s what you want to see. Then you can experiment with subjects in your conversation and gradually move toward something you like. Since ChatGPT uses the entire conversation to make images, rather than single prompts, you can add or remove elements as you go along.
This sample was produced via trial and error with situations involving a funny twist on a calm scene.

Behind them, a boy on a skateboard zooms into the frame with a comically exaggerated expression of surprise, mid-photobomb, adding an unexpected burst of energy to the otherwise calm scene.
