Thousands of years ago, when tools were very primitive, it was probably common to have a favorite rock.

Still pretty common today.

Look at this fella with no favourite rock

Ha, what a ...wait, do you think they also don't have a favourite stick?!?
- Or a favourite cave?
- There was definitely a time when nobody pretended their favorite stick was a gun.
- I have a jar of rocks and two sticks. That guy doesn't know how to human.

Wearing Jewels is the advanced form of carrying a pet rock.

We're not so different than the penguins that prostitute themselves for rocks
- To be fair, the penguins don't care about the rocks they're just kinky like that

This is lemmy. Everyone has a favourite rock.

They're fucking minerals Marie
Hematite is hella tight.
- I had a different one in mind.
I can't pick a favorite.
They're all neat.
Mine is cummingtonite
I thought I was weird after seeing that black stand-up on kill Tony saying he had some of his favorites in his pocket. My step mom and I went hiking and she found two really cool rocks, one was gray and has streaks of purple, the other one was dark but with orange streaks. They live on my dashboard.
- Dashboard, as in car dashboard? Or is that also a name for furniture?

Paleontologists have found Neanderthal stone tools (knapped stone) made with high quality stone taken from kilometers away. This means that they had favorite tools that they wanted to keep with them, while other low quality stones where used few times before being discarded near their collection point

"Yo dude checkout my secret rock spot, it's 13 kilometers over there"
There's an area in the cascade range (western US, specifically oregon) that is a giant field of knapped obsidian, that was used as a training ground for young knappers, as well as a trading ground to trade knapped obsidian that has been found all over the western US. Not just miles, but many many miles. I'll see if I can go find a link.

Wasn't that long ago that people even had pet rocks.

Ehhhhh, believe it or not the 1970s was 50 years ago.
- The 70s will remain thirty years ago until the day I die.
- Can't be. I was born in the 70s and I'm only what the fuck?
- ancient history
- Stfu

I have a favourite rock

Is it this one?
- That's not a rock, that's Dwayne Johnson, you know the actor
- I got an STL on his face on those things that shot at you from the river in ocarina of Time. It's called an octorock

Was?

Wait till this guy finds out about the Kaaba

Glory to your rock house

One of my favorite rocks is stoner rock.

stone? or rock?
- Yes.
- :: eye twitches in dwarven space miner::

Doing volunteer trail maintenance. All the people swarm the tool pile trying to claim their favorite pick mattock or grub hoe. It's adorable.

You're my favorite grub hoe.
- 😍

Umm.. I still have a favorite rock. His name is Doug 😂

My favorite rock also has a name: Mount Saint Helens
- And what a great rock that is. Although temperamental at times.

You don't have a favorite Rock?

Don’t mind Geologists

My favorite rock has a first name, it's H-O-M-E-R. My favorite rock has a second name, it's H-O-M-E-R.

Sea otters exhibit this behavior. They keep their favorite rock in their pouches and use them to crack open shellfish.

Like I have a favorite spatula.

It's believed that connections to objects as favorites is a more recent human evolution. Tribes would have spears and tools but people would just take one.

this reminds me of the kam patterson skit

I have a favourite kitchen knife, so it's plausible

According to archeologists, it was probably obsidian.

Ah, they tried to reach the Nether.

I mean when I was young and used to play with rocks I had a favourite rock, I mean even painting rocks was a thing. No need to go thousands of years back lol
