But then, maybe once a week, usually on a Friday, that bastion of knowledge turns on some Pink Floyd and a laser machine, and the scientists and great thinkers that run the joint turn a blind eye to all the people ripped out of their f**king minds on drugs who come to watch. It's called a laser show, and planetariums must be aware that the typical Friday-night laser show audience is so high they think they're going on a personal journey through the cosmos in a funktastical wondership fueled by Led Zeppelin.

That's the silent agreement science museums have with their city. Seven days a week, you can go there and behave, be sober, and be a proper lover of science and the stars. Hell, bring your kids! And granny! That old bag'll love celestial bodies and exhibits on gravity and s**t!

See? Granny loves it!

But Friday night at 10, leave the kids at home and slingshot some Ambien into granny's head, because Radiohead has something to say to you, the only language they speak is lasers, and LSD is your translator. Show up with your brain looking like a black-light poster and feel like Star Wars is happening in your face! Stare at a wall with flashing lights until your peaceful, meditative high turns into a rollicking f**ktastical hellscape of a bad high and you're huddled in a corner, crying louder than the little kids you've freaked out with your freak out.

Your local planetarium: come for the knowledge, stay because the Bob Marley laser show is about to start and you just scored a dime bag.

Restaurants in mall food courts must be aware that broke-ass kids are filling themselves with repeated offerings of free samples, right? There's no need to grab a sample and then head to Macy's to buy a new outfit to do it all again in disguise. You can wave hello to the person holding the platter and even introduce yourself and supply a detailed family history and the results of a fingerprint analysis proving that you've recently touched that platter -- and they still won't stop you from basically stealing their food. And that's where the unspoken agreement comes into play.

Every food court restaurant is surrounded by competition. They're competing with cheap cuisines for every palate. Add to that the fact that, regardless of the restaurant's theme, most of the food served in the food court is exactly the same. Cajun Grill's dishes are the same thing you'll get from the Asian stir-fry place, which is pretty damn close to what you'd get from the Mediterranean place, which is very similar to what you'd get from the Latin place: meat on top of starch on top of vegetable. Add c*min and oregano and it's Hispanic! Add bourbon glaze and it's Cajun! It's a 10-car pile-up of food scientifically optimized to shut you the f**k up about the lack of food options at the mall.

It takes about four or five bites to fully distinguish one chicken from another, so these restaurants turn a blind eye to slackers like teenage me. Give him all the toothpick chicken he wants as long as he chooses us in the end. At least, that's probably how they rationalize the complete lack of effort shown by the employee holding the platter of samples who has the work ethic of a cowardly castle guard confronting an invading army.

Movie theaters don't turn a blind eye to people squirting their sex fluids on the seats. If people can't wait for a better time to fiddle with each other's genitals than the 3 p.m. showing of Transformers, theater ushers will grab them by the thick stench of sex emanating from their heaving loins and toss them out. It's the common theatergoer who seems to have an unspoken agreement with the fornicators. People are aware that once the theater darkens the back row starts to gush, because a lot of those theatergoers were themselves once horny teenagers trying to bust a nut in the back row of a movie theater. When the sexy stuff commences and the couple does little to hide it, I find that most people just ignore it, hoping the movie is louder than the slurps of pleasure and that the couple reaches orgasm quickly so all parties can get back to enjoying the film.

Finger-banging can actually make sitting through some movies much easier.

No one ever enters a movie theater expecting to see a tangled mass of limbs and spraying fluids off in the distance when they turn the corner of the hall leading to the vast expanse of seats, but it's not surprising, either. I've overheard people blame themselves for sitting in the back row beside a couple elbow-deep in each other. Why? Because in the same way the line "Forget it, Jake. It's Chinatown" from the movie Chinatown reminds Jack Nicholson's character that trying to make the world a better place is futile, we're reminded that it's futile to fight against the sticky tide of people going nuts on each other's junk in the back row of movie theaters.

Just turn your eyes.

Just look away from the f**king and sucking.

Forget it, Jake. It's the back row of the movie theater.

People walk in and out without buying a thing, all day, every day, at those places because they're basically novelty stores, like Hot Topic or Spencer's for people with jobs -- a lot of useless, high-end gizmos, gadgets, and trinkets. The thing is, no one actually wants to spend the money to get what they sell, but they wouldn't mind if the vibrating eye mask with cooling gel that plays new-age covers of Phil Collins songs magically showed up at their house.

People want massage chairs, but very few can justify sacrificing four months of paychecks to get one. So the Brookstones and Sharper Images of the world see nothing but an endless stream of browsers who pretend to care about the glass case of die-cast models of vintage cars that sell for whatever your soul is worth as they wait for their chance to sit in the massage chairs.

And that is the unspoken agreement high-end novelty store employees, and maybe even the executives at the corporate offices, try their best to ignore: a vast majority of people walking through their doors will never, ever buy a damn thing, yet most of the time those people spend in massage chairs over the course of their entire lives will have been tallied in those stores.

If it weren't for those chairs, no one would know what those stores sell. People would walk by and see a bunch of useless items that caught their eye only because they were shiny and expensive-looking, then they'd ignore it all and go back to licking clean their toothpicks of chicken samples.
