A few years ago I had a panic attack on a flight so I started taking Xanax for when I travel. Or when I mistakenly think the bike path is an on ramp (after, not before). Or when I'm bored.
I actually now take 1/2 so that it kicks in as I go through the security check point as I am fairly certain that at some point you will see a video of me being tasered by TSA on your nightly news. Apparently they don't like it when I say things like "are we still pretending shoes are a threat" while I wait. And don't bother pointing out that the official size is 3.3 ounces (or 100 milliliters in EVERY COUNTRY OF THE WORLD EXCEPT THE US, BURMA AND LIBERIA!!!) of liquid, not 3 ounces. Unless you want the pat down.
But to the TSA's credit, their quick thinking has stopped another would-be terrorist from using her terrorist cupcake to terrorize a flight. They have also prevented countless attacks by sharks, one assumes. (You haven't heard of an attack via carried on shark, have you?)
