Grandma carries a knife. She loves apples but can't eat them whole because of her dentures. A knife is so handy for lots of people.
Does Grandma know about all the new idiotic TSA regulations? No. Is Grandma going to hijack a plane with that knife? No. Where's the crime? Where's the victim? Just take the stupid knife, tell her why, and let her go on!
Obviously grandma is working clandestinely with Al Queda.
Admit it, she just hates Freedom.
A likely story. Sounds more like Grandma is a bomb-toting raghead! </ TSA >
