Did anyone else find the ending humorous?

I don't recall the movie being humorous at all, up until the end. I thought it was sort of humorous how naive both Brian and Cassy were as well as myself. Yes, myself. I mean, the couple said it would be their secret what they did with the bodies, however there was another spy cam filming them. And they were oblivious to it. So what they thought was their secret, had just been viewed by probably thousands of people around the world. That sort of surprised me, as I was thinking that the now two dead scoundrels had been doing it purely for their own amusement.
