Yes, it's stuck in my head. Yes it's awesome. No I can't stop watching it. Perfect animation synching to music is something I'm addicted to.

EDIT:

Turns out that is a special music video made for the full song! There are more antics that these two monsters get up to as they torment the telemonster and frog:





Even zombies fear these two. And, of course ,a nod to Thriller.



Seems Eerie doesn't have the same charm as Yossi, but he doesn't let it get him down.



DOUBLE EDIT:

I even found lyrics to the song!

Lock tight your door
Avoid it if you can

A place without light
I pray it's not you and me

Sullivan, Squishy, Oozama Kappa
Terry with an I and Y (x2)

Lets get it started
Scare games
Yes! My time with you!

Tick tock tick tock,time stops, lets play
Shame-
Shame-
Shamelessly having fun by yourself

Monster, monster, no one knows this electric feeling

Dizzy how, dizzy how, Telemonster time

In the cold blood, the moonlight rises
It's a hot start, a new nightmare
Feel the fear from the cry of the night
Hide behind the moon, I can see you

Will you be able to survive the night...
... when I'm looking at you under the moonlight?

Sullivan, Squishy, Oozama Kappa
Terry with an I and Y (x2)

Lets get it started
Scare games
Yes! My time with you!

Tick tock tick tock, time stops, lets play
Shame-
Shame-
Shamelessly having fun by yourself
Monster, monster, no one knows this electric feeling
Dizzy how, dizzy how, Telemonster time.

Run, run, ru-, ru-, run away
Run, run, ru-, ru-, run away
Run, run, ru-, ru-, run away
Ru-, ru-, ru-, run!

Lets get it started
Scare games
Yes! My time with you!

Tick tock tick tock, time stops, let's play
So this ni-, ni-, night won't be over
Monster, monster, no one knows about this scary feeling
Dizzy how, dizzy how, Telemonster time
In the cold blood, the moonlight rises
It's a hot start, a new nightmare
Feel the fear from the cry of the night
Hide behind the moon, I can see you
