I'm really surprised I didn't get "randomly" chosen for a more detailed search last time I flew (last weekend).
1-way ticket to Atlanta, no checked baggage, my luck with authority figures (read: let's all beat Ben down for fun gaiz! he looks suspicious!), and a back pack with only two tee-shirts and a license plate ...
Are you from middle eastern descent though?
I accidentally went through Washington DC Airport to London with a firecracker in my back pocket. This was just after the huge bomb scare with the plastic bottles.
