To my knowledge, all the laws Reid talks about in this story are true (or were true at one time). [Usual disclaimers.]
"I guess I just don't see it," Emily said as she, Morgan and Reid made their way back to the station.
"See what?" Morgan asked.
"The thrill of 'doing it' in the backseat of a car," the woman replied. "I mean, honestly, it's a tight fit and there's no leg room."
"Seriously, I think it's about getting caught," Morgan replied.
"Be hard to do in this area," Reid piped up.
"Not hardly," Emily countered. "Major highway just below us, busy street…I'd say this was the place to 'shack up,' if ever there was one."
"That's not what I meant," the genius countered. "I mean there's an old law on the books that makes, um, 'getting caught' highly unlikely."
"You're kidding."
"No. Apparently, if a law enforcement official suspects that…well, that…is taking place in a parked vehicle, they must flash the headlights three times, honk the horn, and only then approach the vehicle."
"Please tell me you're joking," Morgan said.
"It's absolutely true," Reid said, not giving in an inch. "There's also a law somewhere that allows for fornication in a parked van if all the windows are equipped with curtains that close."
"Where's that?" Emily wondered.
"Utah, I think, or maybe Idaho…"
"You're making this up!" Morgan chortled. "Seriously, how is anyone gonna be arrested for, I dunno, indecent exposure or prostitution in these parts?"
Reid shrugged. "Have to get quicker than the suspected culprits, I suppose. Far as I know, that's still on the books."
"Huh," Morgan said. "What else is there we don't know about?"
"Well, in Michigan there's an old law…but I'm sure you don't want to hear about it, especially you, Emily…"
"Well, now I'm all ears," Emily challenged. "What happens in Michigan?"
"Well, there was an old law that said that a woman's husband was the legal owner of his wife's clothing and hair, and that, if she left him, he was legally allowed to follow her down the street and remove all the clothing from her person and cut off all her hair."
Emily turned around from the front seat to face Reid. "Tell me you're joking."
"I'm dead serious. Though I highly doubt that law's enforced anymore."
The brunette turned back around, a slightly green expression on her face. Morgan sat in the driver's seat, chuckling as quietly as he could. "I bet there's a lot of laws like that," he said, making sure that Emily's hands were nowhere near her sidearm.
"Well, actually, it's illegal for women to pump their own gas in New Jersey…"
"Really?" his colleagues said in unison.
"Yeah. Men must willingly do this for them. I think they got around that one, though, because in New Jersey all service stations of any type are full service."
"You're kidding," Morgan said as Emily bore a satisfied expression on her face.
"Why does everyone think I'm joking? Have you heard me tell a joke?"
Morgan looked at Emily. Emily looked at Morgan.
"All right," Emily finally said. "What else is there we should be on the lookout for?"
Reid merely smiled. There was no way he was giving them the one about the penalty for drinking coffee in Turkey some five hundred years ago…
