We’ve seen this premise before: Two people stumble into a situation where the end result leads to them switching bodies, forcing each person to live as the other for an undetermined amount of time till they figure out a way to switch back. Lately we’ve seen this premise applied to an adult and child (17 Again, 13 Going on 30, Freaky Friday, etc), but in The Change-Up, it’s two adult dudes (played by Jason Bateman and Ryan Reynolds) who wind up switching bodies when they both wish to be the other one while simultaneously urinating into a fountain. Don’t you hate it when that happens?
