I'm not sure if this has been posted elsewhere (I only check the BA forum here), but I just came across this on Consumerist and I found it quite funny.

Warning: the humor may be considered distinctly "American". The video is nonetheless relevant as the airport security rules continually become stupider and more absurd by the minute, and the stupidity and absurdity has certainly managed to cross the pond.

"What if I am a passenger that does not have three ounces with me, but is confident I could produce three plus ounces on the flight?"

"You mean, producing a liquid?"

"Or a gel..."

Enjoy...
