- Oh my God!

- Shh, shh.

(rock music)

- So the only reason that I've never gotten a tattoo

is that I've never known what to get myself.

- Problem solved.

Just take that outta the equation.

I pick something for you.

Everyone wins.

- Unless it's awful.

- We're here at Body Electric Tattoo.

- We are siblings.

- You have something on your teeth.

You have lipstick on your teeth.

- Fix it.

- We have chosen tattoos for each other.

We have not told the other person what they are.

- And we won't know until it is on our bodies.

- Forever and ever.

- We've worked very hard

to have it be a wonderful, supportive relationship,

and it could all just go to hell after this.

- How could we lose?

It's gonna be great.

- I think I trust you.

We spent a lot of our childhood in Colorado,

so there's like a range of mountains, the Twin Sister Peaks.

I drew the mountains.

- Do you want me to redraw the trees

so they look a little more--

- You mean like make it better?

(laughing)

- Yeah yeah yeah.

- Simple geometric design, and combine it with this flower

that is from a picture from the front

of our old childhood home.

- It can be done.

- Oh, great!

'Cause I don't have a backup.

- My sister, my brother, and I,

we all live in different parts of the world.

She lives in London.

We have this unique family connection

we call, for whatever reason, a flavor wavelength.

I know it sounds pretty ridiculous.

It's like our own family's frequency that only we have.

- Sure, right right.

- [Mike] So the word and having it

just kind of subtly transition into like a heartbeat.

- A lot of people kind of believe

that the full moon definitely has a real impact

on the world around us.

He's a pretty big believer in this,

and whenever I see a big moon in the sky,

I'll immediately text him and he gets really excited.

It's like he's sending me good vibes from wherever he is.

You know, kind of like a misty, dark background,

so you can see that it's a full moon,

and then a little bit of like an abstract feel to it.

I'm really excited about it.

I think it's gonna look sweet.

(rock music)

- I am about to get my first tattoo.

- What am I doing?

- All right, you ready to rock?

- Okay, let's do it.

- Let's do it.

(buzzing of tattoo gear)

- You know when you pick someone a gift,

and you're worried if it's gonna be what they want?

- I can't return this.

- It feels like a single cat nail digging into you.

- This hurts a lot worse than I anticipated.

- Ow, it hurts!

- We all know who the tougher sister is.

- Regardless of what it is,

it'll always make me think of you.

- That was quick.

- [Adriana] It's a cartoon penis, isn't it?

- So excited just that it's over.

- I have no idea what was just permanently drawn

onto my body.

- If I don't like it, can I have that scarf

I really like of yours?

- I really wanna look at my arm.

- Whenever you're ready, just take a look at it.

- Oh my God!

It's so cool!

- It's gonna be there for a long time.

- A really long time.

Thank you so much.

- Okay, here we go.

Oh my God!

No (bleep) way.

This is so, Ben, this is so perfect.

- Do you like it?

- Yes.

I know, it's amazing.

I'm so happy.

- Ooh.

- It's a magnolia from our magnolia tree

in front of the house.

- That's really beautiful.

- I thought it was really cool

that we chose different places

that have to do with our childhood.

- Three, two, one.

- Oh!

My God!

Wow!

- Yes?

- Yes!

The moon is my favorite thing in the world.

She'll always text me when there's a full moon.

It's just like another extension of the flavor wavelength.

This is awesome.

- Ben, it's perfect.

Everything about this is amazing.

- This is my style.

Look at this.

It complements the tattoos I already have.

- [Melissa] So, solid first piece of ink on your body?

- Yeah, I'm ready to get a full sleeve now.

- Oh, Jesus.

I'm so happy that you love it.

- When I'm really mad at you,

I'm just going to carve it out.

- I know.

- Now, when you're in London,

you'll always be able to look down

and just remember your brother.

- When are we gonna tell Mom?

(laughing)
