Can someone tell me what happened at the very end?

Rating: Null/10 (16 June 2006)

Alright, when I went to see the movie, I was entranced. I got all the way to the part where they enter their home and saw the dad sleeping on the couch.
But can someone please tell me in detail what happened next? I missed it because a family decided to come in at that time (god knows why at the end) and sat right behind us. While they were sitting, one of the kids refused to sit next to the other one and caused a great ruckus. In the ruckus, the popcorn was knocked and half of it spilled onto me. By the time I looked back, the credits had started.
So, can someone be nice enough to tell me what happened?
