Kinetoscope. I track things like what movies I've seen, who I saw them with, the country of the film and things like that. This year I'm marking down every time I see a film with someone vomiting at some point in the movie. Since the year is nearly half over I thought I'd give an update of the total.
I've seen 118 movies as of June 25th and 15 had some kind of puke scene in it. That's a percentage of 13%. Aren't you glad I'm keeping tabs on this sort of film statistic?
