NO CLOTHES with the exception of a wad of underwear.
You may bring aerosol cans, matches, lighters, a helium can so you can make funny noises while on the plane to make the other passengers laugh.
Oh, and don't forget. They don't make Starbucks the same INSIDE the airport, purchase one before you go in, and bring a doctors note that you will non-functional if you cannot bring it in with you!
