The question is: if it were you, would you want the entire world to be watching this? It's gone viral on CNN. The mother looks amused about it and the son doesn't look as though he's doing this out of any malice--it's just funny to him. If she didn't want it up there, she could ask him to take it down. But once it goes viral, there is no "taking it down." It's endlessly shared online.
This is the problem with our technology trigger-finger culture. Putting up video without someone's knowledge or approval has become the common course of action, rather than the considerate choice, which would be to think first about how exposing someone so publicly might hurt his/her reputation - or provide fodder for more online ridicule.
Ask your kids/students how they would feel if someone did this to them. Ask them if video like this could be used against them in any way? By their enemies? Ex-friends? Ex-relationships?
Any time you contribute anything to the Internet about someone else, it adds to their digital footprint. And some people do not wish to be so exposed at the expense of a joke.
