I went to my first 3D movie the other day with a friend. After it was over my friend put the 3D glasses in a special drop box they have outside the theater. I said I was keeping mine to give to DS to play with. She jokingly called me a thief. I just figured since they gave them to me in a sealed package and I pay more for the 3D than regular, then I am paying for the glasses to and can keep them if I want.
