My girlfriend told me it would be a good idea to start doing this soo- *!!SWEAR WARNING!!* Edit: 0:50 I didn't even notice that frame glitch. Wonder where that frame went- Basically, Sans said "Paps is just tall!" in that frame. Edit again XD: People are getting a bit mad at me for the age thing- I honestly have no excuse except for; I was too lazy to google it XD. This video was made as filler and I honestly rushed it- In newer videos, if we ever talk about the skelebrother's ages- I'll get it right XD Edit x3: I've had even more people correct me on the skelebrother's ages. I looked it up after the second edit and THE SKELEBROS DON'T HAVE CANON AGES Y'ALL. Anything you saw was all fanon. And even then- I've changed their ages in my AU since this video. Sans is now 28 and Paps is 25. Edit 4: I am genuinely surprised people are still commenting on this thing a year later- Why is this my most edited pinned comment?? The amount of times I've been notified for this video almost gave me motivation back to make more undertale stuff lul

Gaster’s like “YES SON I HAVE TAUGHT YOU WELL!”

13-year-old *Snas* must have been a wonderful person to be around.

*monsters get to the surface and need jobs* school: *looking for biologist* sans: time to osteo-outclass everyone

Nobody: Not a single soul: SANS: I am going to edumacate you

I realized he made this up when he was 13🤣😂 1:Smart ass 13 year old. 2:INAPPROPRIATE 13 YEAR OLD!!!! 3:He still makes amazing jokes 20 years later. That's dedication to humor my guy. So many things made me laugh.

I can imagine sans doing this in front of like 100 people

Person: *breaks bone* Everyone else: **insert coffin dance here**

My mind has expanded

Oh my lord. Never let Sans ever come near anything sciencey ever again.

Sans is a better teacher then *Mrs. Dianasoar-*

X3 THAT WAS BEAUTIFUL! 💜💜 Sans: “Homer Simpson.” Everyone: Can’t breathe because their laughing to hard. Toriel: He said that one word! Sans: “Did I do good? I think my explanation is pretty clear. What about ya’ll?” Me: WAIT SANS MADE THAT WHEN HE WAS THIRTEEN!? 0-0

I’m laughing at this but I can’t help feel disgusted by the photos and I don’t know why..... I LOVE IT

Gaster : Sans no! Sans : Sans yes! Me : SANS YES!!!

2:07 LITERALLY IDK IF I WAS THE ONLY ONE BUT WHEN SANS SAID *the word-* Paps looked so freaken confused That is how innocent papy is fam-

Oh my god I turned into homer 14 times now

0:17 he doesnt mess with it PUBLICLY SO THATS WHAT HES BEEN DOIN IN THE BASEMENT LAB RE

I learned more from this than my class sans is smort

Can Sans be my new teacher

Ouchie Bang Bang.

2:07 Toriel is pissed, and Gaster doesn't stop dying for the rest of the video. Also, thank you for reminding me that this hilarious video even existed. I love this video (the original and this one).

Thank you sans you were actuly the best teacher i have right now my others suck at keeping us informed

Sans: imma edumacate u!! Me: OMG I SAY THE SAME THING!!! What a coinkydink

If sans is 33 20 years ago: He made it when he was 13 UWU And papyrus is 26 he was 6 years old when sans made it no confusion

THIS IS AMAZING I HAVE PLAYED THIS ON REPEAT A BAJILLION TIMES AND IT'S FUNNIER EACH TIME

THE FUDGE BRAH? WHAT DRUGS DID YOU TAKEI WANT SUM

This is amazing

Gaster: Sans will be the best teacher when he grows up Future: *THIS*

Look at there faces they like: "sans has a good sense of humor"

If sans was my science teacher I would be more happier going to science class xd

Best version of"Sans explains how the bone is repaired" I've ever seen in my KZfaq life.

Sans: Ouchie bang bang Me: HAHHAHAHAHAAHAH *Dies of laughter*

Sans: ThIS A oUChIe BanG BaNG Me: I have been taught ring my hole life Me: MOM I GOT A OUCHIE BANG BANG

I LAUGHED SO HARD AT THIS. Keep up the good work, you're awesome. Btw, cause of this video, you have another subscriber.

I have watched this at least 3 times over and still haven't gotten over this. This is amazing.

The Homer Simpson thing is what got me

Was not expecting the "blue roombas." That got me wheezin for some reason 😂😂

Highly recommended to watch.

This probably helped me learn this better than any other online lecture could XD

"Ouchie bang bang" is what I'll say when I hit my elbow on the corner of a table

This is freaking hilarious and matches sans perfectly.

2:08 Papyrus is like "hUh?" and Toriel be like.................................... "*IMMA YEET YOU OFF A BUILDING*"

I've never felt so smart in my life until now

I died at the “Ouchie bang bang” and that’s just the beginning 😂😂😂😂 I won’t be breathing by the end of this.

I... LOVED THIS!! It keeps making me laugh!

please make more of those this was hilarious XD

I swear to god this is the first video to ever make me CRY from laughing 😂

WAIT IVE WATCHED IT 3 TIMES AND SANS WAS 13 WHEN HE MAJORED IN QUANTUM AND MEDICAL SCIENCE...…….you fill with determination as you realise all common sence has floated away!

This is one of the only things I've laughed at on the internet

I wish I could like this more than once

Y'know what? We all better donate some hymahobgoblin. Also, nice touch at 1:09 with Sans's eyebrows lol

The real Canon Sans would be proud.

13 year old sans is a riot! I love this!

Why I´m seiing this only now?! o.o This is so perfect

AMAZING THIS IS THE BEST EJECTION SANS THANKS!

Omg yes this is what I needed form making my self cry because of ‘two birds on a wire’ dreamtale edition

yes, thank you for edumacating me, sans when a real school couldnt

YAAAAS MY BOI GASTER IS HERE WOOP WOOOP

Best biology lesson I ever saw

My mom and brother just came into my room so I acted like I was asleep and saw this. Before this I was crying because they turned off my music but this cheered me up alot.

Noone: Not even the gods: Not even us: Sans:"U become Homer Simpson" Me: Pffffffffffffffffffft XD

Look was watching this in my bed at 8:31 AM even before anyone was awake XDDD

1:09 THE SUBTLE EYEBROW LIFT FROM SANS OH MY GOD

I can’t breath 😂 My mom probably think I’m dying I’m wheezing that hard 😂

Amazing! Simply amazing ♥️ ✨

*Gives Dianasoars job to Sans* you're better at it, and you're funny, so you're a mix of funny and smart. Please, do us all the favour of taking Dianasoars job.

I don’t have enough brain cells for this

In the past I wouldve listened to my science teacher if she taught like this lmao

I learned more from this then my science teacher have taught me in 9 years she gave up on me

The homer Simpson part got me

I was actually trying to correct sans on The Osteoblasts bit- oops
