"Good day, sir."
"Good day, Officer."
"Are you a criminal?"
"Uh... wait... let me think.... uh.... yes. No, wait.... No. No, I'm not."
"Ok, on your way then."

Reminds me of the time I went from Oregon to California with a girlfriend who saw authority slightly differently that I do. We had a couple bags of organic veggies and lettuce in the back seat. A few miles before the 'Agricultural Check Station" I nonchalantly threw a my coat over them.
"Good day, sir, do you have any fruits or vegetables in the car?"
"No, sir."
"Ok, thanks. Have a good day."
"You too."
The GF looked at me as we drove off and said "But we do have fruits and veggies!"
"I know. Its called lying."
"Why did you lie to the officer?!"
"Because they're looking for things bought at roadside stands that haven't been sprayed with crap or people trying to import lower cost produce into the highly regulated state. I didn't want to waste our time or his explaining that we bought the veggies at a health food store, that they're organic but still perfectly safe. Nor did I want him to decided our wonderful pesticide free food wasn't safe enough for California and confiscate $75 worth of produce."
"But.... you lied to him! What if he found out?"
"He wouldn't. Searching the car would be illegal unless he had probably cause. That's why I covered up the veggies. It's fine. We haven't done anything illegal, I just didn't want to stop and have to explain that fact to him."
"Oh."
