I had a bottle of Jameson Distillery Reserve stolen out of my checked bag somewhere between when I checked it at JFK and when I retrieved it from the carousel at PDX. It was packed in a cardboard tube inside a plastic bag, packed in the geographic center of our largest suitcase, firmly surrounded by 2 weeks worth of dirty clothes from our trip to Ireland. When we opened the bag at home, we had the plastic bag to remember it by.

It wasn't crazy expensive - $60-$70 iirc, but it was the principle. And the fact that you can apparently only buy that bottle in one place in the world.
