two more excellent comments from the Post:
They should advertise on McDonald's Happy Meals since the behavior of the TSA agents at National Airport resembles a playground at an elementary school rather than serious professionals concerned about national security.
As other commenters have already noted: The pizza box advertisement does seem to be the ideal demographic for TSA employees. The bottom of the Federal Ladder for sure......I'm sure they were meeting resistance on college campuses to have a career in telling people to throw away their shampoo.
