No, really. Yesterday at Target my sister spied a dollar bill wadded up in a bush near the parking lot. I think our reactions said a lot about each of us as we determined whether it was worth it to dig into the bush to retrieve it (after I told her that there was probably a whole family of scorpions living in there):
She - "Do you think it's real or one of those fake bills?" (like the ones that say something religious on them)
Me - "What if it has drug residue on it?"
