OK, I think the joke might actually be that the other person was taking the selfie, and that John is the nervy photo-bomber. Gets a bit muddy because it's on John's Instagram, which inherently suggests that it was his photo which someone else ruined. Thoughts?

But then, I've been working all week-end, and we were very busy, and I might just be the only person who's too slow to get the obvious joke.
