Celestia: Ooooooooh! How many proof?

Luna: Close to 190. I used it clean our clogged toilet and we won't have any problem now.

C: Oh my! Are you sure it is safe to drink?

L: We are immortal aren't we?

C: Immortal doesn't mean invincible, Luna.

L: So, you want the first glass....

C: Nononono! You first.

L: Pffff! Scary-cat.

She was about to pour the drink into a glass but decided otherwise.

C: Ahh! Luna! Not from the bottle itself!

L: Ahhhh....

Celestia stared at her.

C: Well?

L: What?

C: Are you getting blind?

L: No. You look big as usual, sister.

C: Hmph! I'm serious, Luna.

L: See? I'm fine and...

She froze and fall on the ground, her older sister catching the bottle in time with her magic.

C: Luna? Luna! LUNA!!!! Are you okay? Answer me!

She belched loudly.

C: I mean beside that.

L: Wow! I-I'm already d-drunk... Now, THAT'S some strong sh-

C: Language!

She stood up, stumbling.

L: Pffff! S-shut up and take a swig...

C: Uh, Luna? I'm over there.

L: ...... Oh shit I'm blind!

C: Great. Now, what will you do for tonight?

L: *scuff* I'm already working in the night.

C: Be serious!

L: Okay. G-GUARDS!!! C-COME TO ME AT ONCE!!!

Ten guards ran to the room.

Guard: You called, your highness?

C: What are you doing?

L: S-shush. Y-yeah. The s-strongest pony...

G: Uh, your majesty? We are over there.

L: Oh. Bah. J-just listen. I made my own batch of Moonshine and the strongest of you who will stand here will have the pr... pr... will take a swig of it.

Guard2: Uh... P-princess Celestia? What's happening with princess Luna?

C: *sigh* Don't listen to her. She is drunk. And blind.

Guard3: Huh?

G: So... What about what she is talking about?

C: Don't mind her. I...

L: Two swig!

C: Stop it Luna.

L: Half the bottle!

The guards were getting uncomfortable and stared at each others.

L: *groan* The winner get the bottle.... and the princess.

The guards stared at each others.... then began to fight against each other in a battle royale.

C: STOP!!!!!!

They all froze.

C: I want you all out of this room this instant!

G3: And the prize?

C: You all want to go into the dungeon?

They all cheered.

C: Not THAT dungeon. The. Dungeon.

The all looked at each others before rushing to the door. Celestia facehoofed.

C: What was that?

L: Running guards that you scared?

C: You can see?

L: Yep.

C: Since?

L: Oh. I never actually lost sight.

C: So...

L: Oh. I'm still drunk. Come on, just a swig.

C: *sigh* Gimme that.
