I did not find this funny at all.
Yes, it would be funny if this was a movie or a TV show but this is real life.
Yes, it would be funny if the story was relayed to me later (if I was a friend or family member).
It isn't funny when Mom video tapes and posts his antics on-line for the world to see. This is no different than when the parents reward their children to stop a temper tantrum. It's time for Linda to become the Mom.
