But Choi's conclusions are more complicated, even if he's already put more thought into this than anyone in history by two paragraphs ago. As it's estimated that we each defecate once per day and urinate seven times a day on average, what we need here are graphs. So many graphs.

There is no excuse for not using little poop icons on that graph.

Basically, if the number of ladies in the house is equal to or greater than the number of dudes, the seat stays down, period. To make keeping the seat up worthwhile, men have to outnumber women by a certain ratio. For example, in a house with four guys, they only get to keep the seat up when there are two or fewer girls; for five guys, three or fewer girls (if you start adding in variables such as multiple bathrooms and proximity of bathrooms to males and females, then you'd need some kind of supercomputer to figure it out).

So there you go. Now we just need them to tell us which way we should hang the toilet paper roll and our relationships will be smooth sailing.

Fortunately, this is an issue very dear to the heart of computer scientist Burr Settles, because of course it is, and he's found a way to quantify exactly what "geek" and "nerd" mean in our culture. He developed an incredibly nerdy (or geeky?) algorithm to determine how commonly words were associated with each other on Twitter:

Conclusion: Geeks can't read that.

Unlocking that would probably take a much bigger nerd than any of us at Cracked, because we all qualify more as geeks. No, seriously -- Settles' results showed that the most significant differences between geeks and nerds are that geeks are more into pop culture references, tabletop RPGs, and picking out plot holes in Star Wars, while nerds are more interested in academic achievement, the pursuit of knowledge, and formulating complex algebraic equations to answer pointless questions. Here's the data, visualized:

"Gets rocks thrown at" is a major overlap.

If you'll excuse the eye-bleeding choices of font colors, the graph shows that people who spend a lot of time talking about hobbies, movies, TV shows, and comics tend to rate on the geeky side of the spectrum, while more sciency things and words that have something to do with reading (and, for some reason, cello playing) are regarded more as "nerd stuff." No word on the prevalence of neck beards.

Of course, there is a crossover, but it's still in keeping with the general rule. For example, science fiction seems to be equally popular among nerds and geeks. And the word that is both the most geeky and the most nerdy is "gamer." So when it comes to our hypothetical example in the opening, we guess you can just pick one.

We prefer the term "average, normal person" where games are concerned.

According to the researchers, a song is more addictive if the vocalist manages to spit out more words before needing to take a breath, like "She says we gotta hooooold ooooooonnnn to what we've got (breathe) 'cause it doesn't make a difference if we make it or not!" Combine that with Jon Bon Jovi's powerful, high-pitched yelling in the chorus, and you have crack for the ears.

Oddly, it was reported that a key requirement of catchiness is that the singer has to be male. The researchers speculate that we're tapping into some inherent psychological intuition to follow male tribal leaders into battle. Which of course is ridiculous, because who would follow Freddie Mercury into battle? Actually, scratch that. That would be goddamn amazing.

So what about golf? Neil Wolkodoff, director of the Center for Health and Sport Science at Denver's Rose Medical Center, decided to hook a bunch of wires up to some golfers while they played to monitor their physiological changes. The results were surprising even to him: Playing nine holes can burn over 700 calories. The number was highest when players carried their golf bags or pushed a cart, but even if your lazy ass rides around the course on one of those sissy little motorized carts, you're still burning an average of about 400 calories.

But more important is the issue of how training affects the game. Wolkodoff determined that when players had reached their anaerobic threshold -- that is, tuckered themselves out -- their games began to suffer. In other words, being in shape (i.e., having a high anaerobic threshold) improved their golf game. Therefore, physical training can significantly impact your success on the green. According to Wolkodoff, these two conclusions put golf square in "sport" territory.

No amount of training will excuse the clothes you'll be wearing later on the course.

So there we go. Now somebody run the same test for NASCAR.

According to the researchers, the project came about from an argument between the two of them about whether bug-eyed character actor Steve Buscemi was cool. Hansen insisted that he was, while Dar-Nimrod (whose name automatically calls his authority on the subject into question) was adamant that he's not. The objective answer? Yes ... and also no.

See, the surprising result is that when they compared the participants' notes, they discovered that we are using two different (and in some senses contradictory) opinions about what makes a person cool. The most common descriptions were things like "friendly," "confident," and "awesome" ("Brad's a cool guy, he loaned me his juicer!"), but then a bunch of others went for "ironic," "rebellious," and "hedonistic" ("Todd's a cool guy, he just smirked when that biker threatened him! Then he stabbed him in the neck!").

Be thankful he wasn't feeling suave. That's when he breaks out the morning star.

Their conclusion is that one kind of cool, which they called "cache cool," is all about being friendly, socially responsible, good-looking, and confident, while a different kind, "contrarian cool," was more about wearing leather, taking risks, and sticking it to "The Man," like the classic James Dean type.

This explains why we might disagree about whether Steve Buscemi, for example, is actually cool. He may not have the billion-dollar smile of Tom Cruise or Johnny Depp, but a lifetime of playing defiant bad guys might qualify him anyway. It confirms what many of us have long suspected -- if you don't have the looks or the charisma, you can always wear dark sunglasses and start being mean to people.
