Just watched the whole show tonight with the extra 10-minute reveal in the end.
It is "expected" that they would choose firefighters who were affected by 9/11. A very touching and a deserving "family" to receive the Extreme Makeover Home Edition.
It's a nice touch that they revisited all of the projects they have completed in the past to give the viewers updates.
The reveal ran out of time though, so I felt it a bit disappointed not really seeing the whole house. They didn't have a chance to show the humidor! :rolleyes
It is a great episode, (even though it's a nice counter-programming to Friends' finale).
