Because you can't print a flag texture on a stick figure man.

Hilarious and well done.

But as for the Hero's Journey / monomyth... I don't know. It's like you took the 7 most popular tropes off of tvtropes.com. Yes, they're very common story elements. But you could keep coming up with 8th, or 9th, or 47th most common story tropes. Do these 7 really cluster together frequently? Are they common in literature and the classics?

That's amazing. Great Sift!

I am startled that so much hand labor goes into producing each baseball. I always thought they were slightly expensive to buy, but now I think they should cost more.

Also, I've probably watched 40 episodes of How It's Made, and it's almost always Canadian factories. I've never seen what might be called a "sweatshop". Maybe they're branching out.

Wow she has really taken this to the next level. The production quality here is extraordinary.

Yeah I'd love to know more about that one. Pretty amazing.
