There are extra-marital affairs mentioned (along with very brief kissing), and a few references to sex through the dialogue. There's really nothing to be concerned about.

There is a wrecked car shown. Everything is comical, such as when a part of a microphone falls on a baby's head during a baptism. Very mild.

In the subtitles, there were a few uses of "fuck" and other profanities. The language is about average for an "R" rated movie.

There is some casual smoking, and characters are comically offered alcohol by a too-generous host.
