Genetic IQ tests - fail. No one is throwing anyone else to the big lizard. The bride and any of the bridesmaids would be easy to trip up on their long skirts so that you can make your get-away. They are just not thinking.
I laughed because it's real. The wedding party all lined up there on the lawn and the photographer instructed them, 'run at me as fast as you can looking terrified as if a giant Tyrannosaurus is chasing right behind you.' And all of them did as asked.And besides, most of the groomsmen are hoping to get to know the bridesmaids much better later. Hardly going to happen if they were tossed to the ravenous dinosaur. :)
I liked the MIL comment at the source. We DO identify with that.
Fire breathing dragons are much scarier then mere dinosaurs.
