Not enough context. Did he climb in himself for fun and she just snapped a picture for Facebook upon seeing him there? Or did she physically put him in there specifically to take a "funny" photograph? Two completely different situations to be honest.

For example, my in laws have a video of my sister in law as a toddler running down a steep sand dune, she gets faster and faster until she loses her footing, falls face first, and skids about 5 metres down the sand on her face.

It is one of the funniest things a I've ever seen. Apparently her aunt, there at the time, literally wet herself laughing.

However... If the same thing happened but because an adult PUSHED a child down a steep sand dune, that would obviously not be fine at all.
