Funny- every time I fly to the US, I get those little love notes from the TSA left inside my bags when I open them.
My wife once got the treatment trying to smuggle a hard boiled egg into Argentina- she had made it for the airplane, and didnt eat it on the plane. They found it on their magic scanner, and took her aside, confiscated it, and wrote her a bad behavior report, which is stamped, signed, dated, and given to her. It was like being in elementary school again. But if you tried to bring a whole bag full of fruit in, most likely, it would be the ruler across the knuckles.
