- Hi guys, it's Karina. - And it's Ronald, and we are from...
- [Both] Sis vs Bro!
- And today we are going to be finding out the truth
using whatever this is.
- Yep! - (imitates dramatic music)
- (both imitate dramatic music)
- So basically, we're going to take the lie detector test on each other
and find out the truth.
- The truth! - (both imitate dramatic music)
- So, who goes first? - Rock, paper, scissors!
- [Both] (yelling) Rock, paper, scissors, shoot!
- (awkward silence)
- [Both] (yelling) Rock, paper, scissors, shoot!
- (both laugh)
- [Both] (yelling) Rock, paper, scissors, shoot!
- (punch sound effect) - Ow!
- So Ronald's going to go first.
We're going to have some serious questions with him,
and see if he's lying.
- "If I like chocolate."?
- (in a sudden manner) Yes!
- (gasps loudly, then yells) - If you truly love chocolate.
So Ronald, put this on. It goes around your waist.
- Almost there. - There you go.
Deh-neh-neh. Is it secure?
No showing nipples, Ronald. - (giggles) Nipples.
- Alright, and these go on your fingers, I think.
Put this on your index finger, and put this on your middle finger.
The middle thing has to be touching your finger.
(in a sing-song voice) Your knuckles, your knuckles.
- I don't like my knuckles. - (giggles)
And this one's going to measure how much you sweat!
Alright, Ronald, you need to remain perfectly still.
No jumping, no screaming. You got that?!
- (suddenly yells)
- (reads inaudibly)
So, Ronald, (inaudible) to this test?
- Yes, but I'm sweating.
- Alright, that's good. Let's start!
"Answer each question truthfully with a 'yes' or 'no' answer."
So, the first question is, "Have you ever lied to me?"
- Yes, many times.
- "Do you brush your teeth every single day?"
- No. - (muffled) Ooh!
The third question, are you ready?
- Yes. - "Do you fart in class?"
- Yes. Sometimes, though. - (giggles)
Next question, "Do you ever eat a booger?"
- No. - I don't believe you in this one,
but we're going to find out. - And it's going to be be true.
- Ronald, no. No moving, no moving, no moving.
"Did you ever poo in your panties?"
- Yes, when I was little.
- No, you pooed when you were eight!
- (suspense sound effect)
- No, you did. I remembered Dad carried you up to the
bathroom.
You've pooped in your pants. - (both chuckle)
- That's not true. - No, it is.
We will find out.
Fifth question, "Did you ever steal a cookie?"
- (both burst out laughing)
- Umm.
No. - Are you sure?
- M-hmm. - We'll find out the truth
very soon!
"Did you pick your nose today?"
- (awkward silence)
- Did you? - No.
- (both imitate dramatic music)
- Next question. - Yep.
- "Did Mom feed you at dinner?"
- (awkward silence)
- Which one?
- Any. - Yes.
- When you were eight?!
- Maybe. - (muffled) Mmm!
Next question, "Did you ever pee in the pool?"
- No. - Alright.
"Am I more funny than you?"
- No. - (gasps)
"Do you keep your room clean?"
- No. - (muffled) Ooh!
This time, I think he's telling the truth.
- I'm lying, by the way.
- What?! - I'm lying.
I'm just joking.
- "Do you have a crush on anyone?"
- (calmly) No.
- Are you sure?!
- (calmly) Yes.
- Are you sure it's not me?
(giggles) - No.
- So, we're ready to unveil the truth. - (inhales through teeth)
- First question, "Have you ever lied to me?" You said,
"Yes," but the computer says it's undetermined.
So we'll never know for sure. - (inhales through teeth)
- Mmm. Lucky (inaudible).
Alright. Next question, "Do you brush your teeth
every single day?"
You said, "No,"
and that is true.
- Yes!! Yes!
- "Do you fart in class?" You answered, "Yes,"
and that's true. You answered truthfully.
- Yes!! - And I guess you're very stinky.
- (chuckles) - Very stinky.
"Did you ever eat a booger?" You answered "No," and
that's true.
- Yes!! - You've never ate a booger.
- Yes!
- Which I'm kind of glad.
- (laughs silently, then looks creepily at camera)
- Alright, next one.
"DId you ever steal a cookie?"
You said, "No," but
that was a lie.
- (gasps, laughs silently) - You lied! (giggles)
You stole a cookie!
- Oh, my goodness. The truth came out.
Out loud! - "Did you pick your
nose today?" You answered, "No," and
it is the truth.
- Yes!!
It's just because I didn't have any boogers
today, maybe tomorrow.
(gasps) - Eww.
Eww!! - (laughs)
- Alright, next one. "Does Mom still feed
you at dinner?"
You answered, "No," and
it's undetermined!
- Yes! - Hmm...?
- You will never know.
- "Did you ever pee in the pool?"
You said, "No," and
it's truthful. You never peed in the pool.
- I knew it! I knew it! I--!
- Next question, "Do you think I'm more funny
than you?" You said, "No,"
but that's a lie!!!
(giggles) You think I'm more funny than you.
- This machine is broken.
You guys comment in the comment section down below.

- I bet it's me.
- I bet it's pee.
Let's move.
- "Do you keep your room clean?"
You said, "No," and
it's truthful. - Yey!!
- "Do you have a crush on anyone?"
You said, "No," and
it's truthful.
- I knew it!!
- Alright, so that was the last question.
It's my turn now!
- And we are going to find out things about Karina!
First of all, Karina's the biggest liar on Earth.
- N--! No!
- First question, "Have you ever lied to me?"
- No.
Well, maybe.
- I clicked "No". - Okay, whatever.
- Second question, "Do you brush your teeth
every day?"
- (awkward silence)
- (stammers) Just one night.
(stammers) But I brushed it twice in the morning.
So... - So, yes or no?
- When I was at night and at the day, I brushed
it twice, so yeah.
Yeah. - We'll see if she's
telling the truth.
(imitates dramatic music)
"Do you fart in class?"
- No. - Okay, okay, okay.
We'll see, we'll see.
"Did you ever eat a booger?"
- (grossed out) No!
- Karina, next question.
"Did you ever poo in your pants?"
- (smacks lips) Yeah.
I remember when I was really little, like, 3-ish,
I hid in a closet with my poo in my pants.
So my Mom won't find me.
- (both laugh)
- I did not need to know this.
"Did you ever steal a cookie?"
- (smacks lips) Did I?
- Mmm? I remember what you said a while ago in some
Gummy vs Real videos.
- No. - How come I don't believe in this?
Do I see a sweat under your nose?
- No? - Karina picked her nose!
- No--! - (laughs)
"Did you pick your nose today?"
- No? - (inaudible)
I just saw you!
- That's not picking your nose!
Picking your nose is sticking your finger up your--.
- Okay, chill. The lie detector will tell the truth.
"Does Mom still feed you at dinner?"
- No. Or you.
- The lie detector is
analyzing her lies.
"Did you ever pee in the pool?"
- (silence)
- Maybe once or twice?
- (suspense sound effect)
- "Am I more funny than you?"
- No. - We'll see.
Next question, "Do you keep your room clean?"
- Most of the time. So I guess, yeah.
- "Do you have a crush on anyone?"
- No.
- Yes or no? - No!
- Okay.
So, that was the last question.
Now, let's reveal the test results. (snaps both fingers)
Karina, the machine has detected some lies.
Would you like to explain any of your answers?
- Umm, yeah. They're all truth.
- Okay! Exam is complete.
Alrighty. So, the first question that you said,
"Have you ever lied to me?"
You said, "No," truthful.
- (mumbles) Uhh-huh.
- I am so surprised. - Mmm-hmm!
The machine is broken.
"Do you brush your teeth everyday?" You said, "Yes,"
truthful. Let's see if they're - (nods) Mmm-hmm.
- all trues.
"Do you fart in class?" You said, "No," truthful.
- (inaudible) - Oh, my goodness.
- By the way, I never fart.
- Ugh, I smell some right now.
- (slaps) Ronald! - (laughs silently)
"Did you poop in your pants?" You said, "Yes," trut-- truthful.
But, of course. If she said, "No," that would be obviously
a lie.
"Did you ever steal a cookie?" You said, "No," truthful.
- Mm-hmm. - Are these all true?
- Yeah, of course they are.
- Karina's the biggest liar. I can't believe this.
- No! Can't you see? Everything says, "True".
- "Did you pick your nose today?" You said, "No," truthful.
- Mm-hmm. - "Does Mom still feed you at dinner?"
You said, "No," it's a lie!
- What?!
- Next question, "Am I more funny than you?"
You said, "No," undetermined!
- That counts as "true". - No, that doesn't.
- Yeah. - It doesn't, though.
Okay. Next question was, "Do you keep your room clean?"
You said, "Yes", it's undetermined!
(laughs) - The computer gets confused,
since it's so incredibly true.
- The next one was, "Do you have a crush on anyone?"
You said, "No," it's truthful.
- Of course it is!
- So guys, that was the last question.
What do you guys think in the comment section down below?
Do you think Karina was lying or telling the truth?
I think she was lying. - I think the machine is broken.
- Me too.
