Transcript Excerpt

Starting point is 00:00:00 Four, three, two, and boom. That's a nice hat. I've told you already, but live, I gotta tell you, that is a nice... It's very kind of Indiana Jones, but... It's not quite that, and not quite cowboy. Yeah, you're like in the middle of that. Yeah, yeah. You're riding the wave. Starting point is 00:00:20 You're dancing on the edge. Look, I have a really fat head, and so there's this website called bigheads.com. There's a website for it? Yes, a total website for fat-headed people. I've got to get my friend Bert Kreischer a hat, then. I put his hat on. I couldn't believe how big his head was. There was like an inch gap all around my head. Starting point is 00:00:37 I thought I had a big head. Yeah, so if you know your head size, do you know your head size? No, I do not. So it turns out if you know your head size, that number comes from somewhere. Can I tell you what it is? Sure. So if you measure the circumference of your head, just get a tape measure, like you're measuring your waistline, but do it around your head, and take that number, divide it Starting point is 00:00:57 by pi, then that's your hat size. Whoa. Yeah. Seems complicated. Divide by two? Why can't it be just like your waist, 32? You know, your waist is what your waist is. I know, it just is what it is, right? Starting point is 00:01:10 Why can't it just be the circumference, right? So what it turns out to be, so what that means is, if you're dividing by pi, you're getting the diameter of the circle that has the same dimension as the circumference of your head. So if you have an oblong head, then what it's doing is finding out what the circle is, the diameter of the circle that has that same circumference as your head. Oh, okay. And that's what that's doing, for whether that helps the hat maker. So immediately I started thinking about Dan Aykroyd on Saturday Night Live as a cone head. Starting point is 00:01:44 Oh. Right? Remember? Well, then you need a tall hat for that, too. Y...
