Dumb Movie Rating Reasons

These days a lot of movie ratings from the MPAA are accompanied by reasons. I was looking at the trailer for In The Shadow of the Moon and it is rated PG for, in part, "incidental smoking."

As if there is such a thing as non-incidental smoking? Smoking is an event and therefore always incidental! But I digress.

What's the dumbest movie rating reason you've seen, and for what movie?
