Caveman Bob: Wow I’m starving, wanna grab some grub?
Vegan Kate: Sounds great, I wonder if this place has quinoa…
Caveman Bob: What the hell is keen-wah? We don’t have that where I’m from.
Vegan Kate: No way! It’s so awesome, plus it’s a complete protein so if you can’t find beans it’s no problem.
Caveman Bob: Beans? Complete protein? Stop talking crazy. If you want protein why don’t you just eat some delicious cow? Cow is delicious. And it’s chock full of lysine. Beans-shmeans.
Vegan Kate: Oh no, no no no. I could never eat an animal or animal product. Not only is it cruel, it’s unhealthy. Animal fat causes heart disease and animal protein causes cancer. Everyone knows that.
Caveman Bob: That’s silly. I don’t have heart disease or cancer and I eat animals for a living. You should see my blood work, it’s pristine.
Besides, I haven’t even evolved to eat those weird cereals and beans you speak of. I’ve been told they’re the reason people have all these crazy diseases of civilization. Thanks, but I’ll pass.
Vegan Kate: What do you mean you haven’t evolved to eat them? We’re physiologically the same and I eat them all the time. I don’t have any of those diseases either, and my blood is also impeccable.
I’m certain it’s because I don’t eat animals.
Caveman Bob: Well I’m pretty sure you’re wrong.
Vegan Kate: And I’m pretty sure you’re wrong.
Caveman Bob: Hmm. Sounds like at least one of us is wrong. Can I get you a drink?
What don’t you eat?
