Pretty smart. I receive credit card offers in the mail, replete with an unusable plastic card which looks like a real credit card (guess they think I'll grab the phone and beg for the real thing). If you or your parents have received similar offers, keep the "fake" cards for future use in your dummy wallet. Sticking a dummy wallet in your back pocket could keep you from an unpleasant close encounter with a long knife in Tunisia, evidently.
"We are all travelers in the wilderness of this world, and the best we can find in our travels is an honest friend."
