Oleg Volk created this TSA checkpoint sign in 2008, which is now getting attention due to recent abuses by the organization.
Interestingly enough, the social location service Loopt is offering 10 iPod touches to people who check in to an airport using the app on November 24th, and tweet about being pat down by the TSA.
As a slight gift to opt-outers out there, Loopt is giving away 10 iPod Touches for TSA touching. Just check into your airport on Loopt* on Wednesday, November 24 (with iPhone, iPod Touch or Android), share a bit about your experience, push it to Twitter with the hashtag #touchedbyTSA, and you can win an iPod Touch. That simple.
