Airline Security Theatre

I haven't flown since before the liquids ban came into effect, and as I now collect all of my precious 3oz liquid containers into the requisite 1-quart plastic bag, I'm terribly tempted to write "SECURITY THEATRE PROPS" in black magic marker on the outside of the bag. Somehow I don't think it'd go over, but who knows? Maybe it could be the start of a sort of education campaign.
