Things that I would not allow on airplanes as additional precautions as well as liquids and gels.

1. People who like to have long conversations about thier "doggies"
2. People who think showers happen as often as the Olympics.
3. People who think that the Santa Clause 2 is gut-achingly funny and proceed to laugh so loud that you can here them over the engines five rows away, even though you are wearing an I-pod.
4. Anyone with a bladder problem who requests a window seat.
5. Anyone with a Taliban duffle bag.
