#2 is awesome, best prank ever! I bought a bunch from Amazon.

Simply Sneezing would stop much of this...

Hardcover books are still legal to carry. That would make some of these toe-jam offenders regret their choices. Accidental drop, sudden close, smash (I thought I saw a bug).

Pour soda on those nasty feet!

Half of these are driven by the attitude of: I'm the most important person in the world.

I'm allergic to perfume, and morning flights are like being sprayed with mace. The burning, itching, choking, coughing, can barely be alleviated by wrapping my head in my carry-on blanket and two masks these days. And the Halitosis three seats away from over-brushes is noxious too.
