I'm not making fun of it. The hypothesis sounds reasonable to me. I just had this vision of a huge 'ttitanosaur rearing its neck up in surprise with a young Majungasaurus hanging on. Take a look at my tyrannosaur family scene. The scene is possible, and the humor comes from the young ones bothering the parents.
Actually, if something brings no reaction to me, one way or the other, I see it as being useless as art. Think about it.
So please, don't have your feelings hurt. That was the last thing on my mind.
