Expedia "Smooth Talk"
A wonderful choose your own adventure video style experience with Facebook connect customization, sadly it is not online today but was an amazingly rich web experience for any fortunate enough to play.
The concept was to explain via video why you had certain "surprise" items in your luggage. Once completed you could pack "surprise" items in a friends bag and watch them try to explain online. The best smooth talkers won a trip to vegas.
