The first was a cryptex as a result of being one of the first 10,000 to complete The Da Vinci Code Quest on Google, a joint promotion for the upcoming Da Vinci Code movie and for Google's personalized homepage, which I already used. As there's only 10,000 of these, they're going for around $60 on ebay right now.
The second item was from the Airplane: Don't Call Me Shirley! Edition DVD that I got a while back. There was a free mini inflatable Otto the Pilot offer that came with the Airplane! DVD, which I obviously could not pass up. (I see one going on Ebay for $30) And of course, true to the movie, they put the inflation tube on his belt.
