This reality is #S-034. In here, all of Lincoln's sisters were swapped with each other in the order they were paired in, and as a result, they cause much more chaos that you would expect in our reality. Lincoln, who's gone completely insane, tries to get rid of them with his trusted friend and sidekick Clyde, who, despite hating the idea, tries to support Lincoln in any way possible.

It's night, and Lincoln is sitting in the garage while mixing some of Lily's stolen chemicals, Lynn's ritual book, Luan's guitar and other stuff from his sisters to create an untimate weapon. Clyde, meanwhile, was on a treadmill, watching Lincoln inventing.
- Gee, Linc, what are we gonna do tonight? - Clyde asked with an interested tone.
- The same thing we do every night, Clyde... - Lincoln said maliciosly, before turning to his friend. - TRY TO ELIMINATE MY SISTERS!
The lightning striked outside, which meant danger...

They're Linky and the Clyde,
They're Linky and the Clyde,
One has wit, and the other has pride,
They're buddy and a friend,
Their friendship will never end,
They're Linky, they're Linky and the Clyde, Clyde, Clyde, Clyde...

Lincoln was walking around the garage, reading his list of failed plans.
- Oh, Clyde, my dear friend, i tried everything! - Lincoln dramatically started. - I tried to poison them, i tried to hang them, i tried to trap them in my glass box until they suffocate... Heck, i even memorized every prank Luna pulled on us on April Fools, and they all failed!
Clyde wasn't listening to his friend, because he was looking at the photo of Leni.
- Clyde, are you even listening to me?! - Lincoln shouted, causing Clyde to throw the photo away.
- Uh, well... What was that again? - Clyde said, completely confused.
- My God, Clyde, will you ever stop being so stubborn... - Linc facepalmed, earning a shy look from his friend. - Anyway, onto the subject. How will we eliminate my sisters? Have any ideas, Clyde? Clyde?!
- Oh, sorry Linc, i was just listening to Mick Swaggers' new song. - Clyde showed him the said song. - He is amazing, don't you think?
- No, i don't think it's amazing, i don't like to listen to rock music, and i especially don't like... - suddenly, the idea flashed in Lincoln's head. - Wait a second... Clyde, are you pondering what i'm pondering?
- I think so, Linc, but if babies are 78% water, and if i could walk on babies, wouldn't that make me Jesus? - CLyde answered, causing Lincoln to facepalm once more.
- No, Clyde, it's not... Ugh... Forget it, let's just get to the plan. - Lincoln showed Clyde his family photo. - In what word can you describe my family?
- Obnoxious? - Clyde guessed.
- Correct! Although it's not the word.
- Annoying?
- Higher.
- Irritating?
- Higher...
Clyde tried to think of a word, and then finally got it.
- Oh, i know! Loud!
- That's it! And i thought you were stupid! - Lincoln congratulated his friend, making Clyde's face turn angry. - So, my plan is, if i turn up the volume, their heads will literally explode!
- That's... Great, i guess... - Clyde was sad at the thought of his friend's family dying, but friendship is more important, so he ran along with every plan Lincoln made.
They went out of the garage and entered the house, where everyone was already asleep.
- Okay, whatever you do, don't do anything idiotic. Just stay in here and wait for me. - Linc sneaked upstairs to Luna and Luan's room, stealing Luan's guitar and loudspeakers.
- Clyde, shut your ears. - Lincoln said to his friend, turning on the guitar. - Because we're gonna rock tonight~ Lincoln shoved Noise-B-Gone earmuffs into his ears and strummed the guitar, as the soundwave came across the entire house, shattering windows, glass objects and Loud sisters' eardrums.
- Success! - Lincoln said as he heard his sisters scream in pain, nearly losing his balance. - 150 dB, baby!
While Lincoln gloated, Clyde was screaming in pain, rolling on the floor.
- We did it, Clyde! My sisters are no more!... Clyde? - Lincoln asked his friend, noticing that he was deafened for life...
