I heard of that a while back. Its now my reason for making noise at a check in to some venue who wands people. If I am going there I have a piece of an IV bag (marked volume part) just inside my belt in front.
I cannot wait to have to show that. It will be one brouhaha. What-- your machine is detecting a colostomy bag? You want to see it? Stand still you will quickly have all kinds of #@*! on your shoes. Probably up your shirt too. As I start to untuck and expose plastic.
I guarantee it that will be the end of the incident. I will make it loud and embarrassing for all those involved. Except me. I can be the loudest, most obnoxious bastard you ever ran into when I want. And its fun.
