Omg better than the original. He made it his own. Can’t wait to see this guy live!
What has been your worst "nice guy" experience?
So, possibly one of the coolest things I’ve ever seen. I mean you know how you hear the “women want him, men want to *be* him” stuff in old movies? Well I’m a man and by *god* I wanted to be this guy. Anyway!
I’m having dinner with my girlfriend at the time, and behind us are a couple on a date. It is.. not going well. Guy was being rather creepy and making some pretty inappropriate comments, the girl doesn’t look at all comfortable.
The girl finishes her appetiser really quickly, my guess is she wanted to get it over with. Guy proceeds to comment on it and says “well, least I know you can swallow right?”. Loudly.
Girl goes red and tells him that isn’t appropriate, he literally waves his hand in a “shoo” type motion and says “oh calm down I was going to find out in a few hours anyway”.
I missed her exact reply as she moved to a hushed tone, but it was fairly obvious what was being said - fuck no, fuck off, fuck this. He responded with “sweetheart I picked you up, I know where you live”. She lost the colour in her face and said nothing.
No. No. Fuck no. I’m one of those “get involved” type of people and there is no way I’m sitting here watching this go down. I get up. I don’t know what I’m going to do, but I’m 23, fighting fit and happy to put that motherfucker through a wall. I may have had a slight temper in my youth. But anyway.
I was halfway out of my chair when a hand came down on my shoulder and I look up to this mid-50s but super fit guy who says “Easy.. I’ve got this one son”. Absolute, total confidence in his voice.. so seeing as my current plan amounted to “stab him in the neck” and I’m already thinking maybe that’s not the best idea, I sit down.
He walks over, grabs a nearby chair, flips it around and sits down with the couple. Then.. he pulls out his police ID and puts it on the table. Now the guy doesn’t have any colour in his face.
Cop: “So, I’m quietly celebrating my daughters birthday with my family when I distinctly hear you threaten this young lady, would you care to explain yourself?”
Guy: “I, ah, well, um, you see..”
Cop: “That’s what I thought. Now see, we take a *very* dim view of that kind of thing, so right now I’m deciding if I want to have some of my buddies come pick you up.”
Guy: “oh no well that…”
Cop: “But that would disrupt everyone’s dinner, so how about you hand me your ID, because I wouldn’t want you running off on me, then you go see one of the staff here and settle your bill.. the full bill now, this young lady shouldn’t go hungry on account of your poor behaviour. Or we can go with the first option, I’ll leave it up to you.”
Guy: “No no! That’s perfectly fine!” \*hands over ID, gets up and walks very quickly in the direction of the counter\*
Cop: \*while writing down the guys details\* “Sorry about that miss, I hope I’m not intruding it just seemed like you could use some help. Oh and don’t worry, if you want to pursue this further I’ll have some of the boys pick him up on his way home, we can definitely take this further.”
Girl: “No, thank you so much, I wanted to run out 30 minutes ago but he drove me here”.
Cop: \*shifts from hardarse cop to comforting father figure in about half a second\* “Well I’m here with my daughter, she’s about your age, perhaps you’d like to finish your meal with us? We can run you home afterwards if you’d like, unless you’d prefer to call someone else?”
Girl: “Oh.. that would be really nice.. thankyou so much!”
\*guy returns, so does the hardarse cop\*
Guy: “Uh so, I’ve paid the bill, if I could have my ID back..”.
Cop: “There you go.. now I have your details right here so I *highly* recommend you don’t go near or contact this young lady ever again.”
Guy: “Yes yes of course, I’m so sorry!”
The guy pretty much fled the restaurant, the girl went and sat with the cop and his family and by the time we left they were still sitting around talking and laughing about random crap.
It was hands down the best way I have ever seen anybody handle any situation, ever. That cop is my hero.
Omg so funny

What is Group Theory?
In math, a group is a particular collection of elements. That might be a set of integers, the face of a Rubik’s cube–which we’ll simplify to a 2x2 square for now– or anything, so long as they follow 4 specific rules, or axioms.
Axiom 1: All group operations must be closed, or restricted, to only group elements. So in our square, for any operation you do—like turn it one way or the other—you’ll still wind up with an element of the group. Or for integers, if we add 3 and 2, that gives us 1—4 and 5 aren’t members of the group, so we roll around back to 0, similar to how 2 hours past 11 is 1 o’clock.
Axiom 2: If we regroup the order of the elements in an operation, we get the same result. In other words, if we turn our square right two times, then right once, that’s the same as once, then twice. Or for numbers, 1 + 2 is the same as 2 + 1.
Axiom 3: For every operation, there’s an element of our ground called the identity. When we apply it to any other element in our group, we still get that element. So for both turning the square and adding integers, our identity here is 0. Not very exciting.
Axiom 4: Every group element has an element called its inverse, also in the group. When the two are brought together using group’s addition operation, they result in the identity element, 0. So they can be thought of as cancelling each other out. Here 3 and 1 are each other’s inverses, while 2 and 0 are their own worst enemies.
So that’s all well and good, but what’s the point of any of it? Well, when we get beyond these basic rules, some interesting properties emerge. For example, let’s expand our square back into a full-fledged Rubik’s cube. This is still a group that satisfies all of our axioms, though now with considerably more elements, and more operations—we can turn each row and column of each face.
Each position is called a permutation, and the more elements a group has, the more possible permutations there are. A Rubik’s cube has more than 43 quintillion permutations, so trying to solve it randomly isn’t going to work so well. However, using group theory we can analyze the cube and determine a sequence of permutations that will result in a solution. And, in fact, that’s exactly what most solvers do, even using a group theory notation indicating turns.
