A video doesn’t appear to be available online, but here’s the script.
Chris: You want to name some liquids, and/or some gels!
Dane: Liquids and gels.
[ no response from the stone-faced recruits ]
Dane: Anything you've got!
Dane: [ pleased ] Water! That is a liquid! Good!
Chris: Bingo!! That is a gel!!
Dane: [ smiling ] Wow! you guys are doing great!
UPDATE (9/2010): A link to a video of the sketch is here.
(Information for our foreign visitors after the jump)
The TSA is responsible for security at American airports. The gel and liquid policy was put into place after the 2006 Transatlantic Aircraft Plot, where participants planned to bring liquids onboard airplanes and mix together the chemicals to make liquid explosives.
