"Okay guys, I want you to go out and find those bank robbers!"

"Chief, how do we find them?"

"Yeah, do we just stop people and ask them if they're bank robbers?"

"Ha ha ha. Chief is so dumb."

"Hey, maybe we can take out an ad in the paper asking the bank robbers to identify themselves."

"Ha haha! There's no way we can find them, Chief. We don't even know their names."
