Silly Places for a Sexual Encounter

This was my response to this week's Terrible Poster Tuesday winner.

I don't like to nitpick, except when the door has been opened to nitpicking. Aren't piranhas fresh water fish? Wouldn't they die an agonizing death in the ocean? And as to sex, wouldn't that rubber raft collapse if one attempted to have sexual relations on it? I've heard of, and might consider sex on the beach, but not sex on a rubber raft in the middle of the ocean. That is an activity which is destined for failure.
This ridiculous poster may fit the movie quite well, actually, as the premise is rather silly.
