There is a scene where Owen Wilson is seen showering on a beach, and flashing his "drillbit" (@ 01:05:22). A PG-13 movie is hardly the place to include such information. Just saying. I'm sure it could have been edited out by the filmmakers... but it wasn't. They just "left him hanging".
I can't say what I would have rated the movie without that there, because it was THERE. It's not supposed to be, and I'm sure they knew that.
If you're watching the movie with your kids, just know what you're in for. I didn't expect it, and I'm sure no one else would either. Just a heads up. - Emha
