Within about 90 seconds, viewers are treated to their first joke about a diarrhetic baby shooting a stream of fresh poop into someone's gaping mouth. That pretty much sets the tone for this foul amalgamation of '80s body-swap comedies and 2010-and-beyond sex comedies. Jason Bateman and Ryan Reynolds play a passive husband and a lecherous ladies' man, respectively, who switch bodies. Lessons are learned, boobs are exposed, and there are plenty more toilet jokes to go around. On the plus-side, Leslie Mann continues to be awesome and Olivia Wilde has never looked lovelier. 101 minutes R.
