I bought a sausage at a grocery store in Germany and hoped to bring it back, but after reading the customs rules as we approached the Philadelphia airport decided not to try sneaking it in. So I told the customs folks I had it and, of course, they seized it. I am convinced the customs inspectors had a nice little snack that day.
