When I threw bags for the airlines I remember a passenger getting the runaround for having placed a tin foil covered piece of cardboard in the bottom of his rollerboard with the words "****** the TSA!" cut out of the tin foil.... the gentleman ultimately was detained and missed his flight because of their lack of humor, character, respect for the traveling public we made it a point to upgrade this guy to first on the next flight out and up until the day I left that unmentioned airline we stuck it to those morons everyday.

Sidenote: IF you were to do the same and were subsequently detained you have a profitable law suit.... we saw the same passenger come back through our city about a month later with his lawsuit printed in the paper. Way to go freedom of speech.
