It all started with Naruto getting an idea to throw Sasuke into a lake because ' proper ettiquet in the presence of guests is to join into the activity and participate as well' - or that is what Ino told him once, and it just so happens to be that the other 3/4 of Team 7 was swimming. Now stuck traveling home with a Sasuke who is extremely polite and social, the exact opposite of what he really is, the team is going crazy, just 3 more days till they get back to Konoha for Sasuke to stop. He will stop right?
