idea for those mouth and nose protectors

ever since h1n2 has hit the streets people are taking a real liking to preparing for impending doom by purchasing those masks that "protect" you from the outside world. anyways, i think they should make masks that have different expressions on them. perhaps a five pack with various emotions so you can switch it up daily depending on your mood.

this idea also helps doctors when they are in surgeries and things. they could have some with smiles but also they could have words on them like "don't worry, i know what i'm doing" or "you're probably not going to die".
