Years ago, when my grandson was in elementary school, I would occasionally drive him and a few of his buddies to a movie or baseball practice. They were a noisy and unruly bunch, and the topic that amused them most was, er, digestive problems. Mostly farting, but they also enjoyed talking about belching, vomiting, and diarrhea--or anything else that was gross. Twenty years later, and this mindset has taken over the film industry. I just watched the movie Bridesmaids. Vomiting, diarrhea? You want it, you got it.
