Loaded guns. A passenger was arrested after TSA officers found a loaded firearm concealed in her chest area at an Orlando International Airport security checkpoint on November 15. (The ammunition was loaded backwards.)

No grenades (or replicas). In November alone, TSA officers discovered a replica grenade in an Atlanta passenger's carry-on bag (left), an empty grenade (center) during checked bag screening at the Detroit Wayne County Airport, and a baseball grenade during checked bag screening at Arkansas Fort Smith Airport (right).

No knives please. These knives were found by TSA officers at Pittsburgh International Airport over the summer.

No bludgeons. Exercise weights and other heavy items that could be used as weapons may not be packed in carry-on bags. These weights and a vice grip were confiscated at airport security checkpoints at John F. Kennedy International Airport in Queens, New York.

No self defense equipment. That means no brass knuckles, pepper spray or martial arts weapons in your carry-on bags. (It's fine in your checked bags, including sealed pepper spray.)

No flammable liquids. Flammable liquids are not allowed, even if you're carrying less than 3.4 ounces. These two cans of lighter fluid were discovered in checked bags at San Diego International Airport.

No fireworks. These fireworks were discovered in a carry-on bag at Chicago Midway International Airport in June but they're not allowed in checked bags either.

No bleach, please. Whatever bleach or turpentine you need for the holidays, why not buy it at your destination? The TSA bans liquids that could make people sick if opened or spilled. Don't check them in your luggage either.

No wrapped presents. Well, you can wrap them, but the TSA may have to unwrap them to check them out. Why not wrap them at your destination and spare your traveling companions seeing their presents in advance?

Don't make them the bad guy. The TSA doesn't keep your stuff. If you don't remove your banned items from the airport, a local or state agency that collects abandoned stuff will often take and re-sell the items.
