The Eddsworld opening for "Trick of Threat"
Late at night on Halloween
Tom and Edd were fast asleep
and said "Trick or Treat!"
But suddenly, she was on the screen
The lights flickered, this wasn't a dream
Edd ran out to save Matt's life
and Edd fell to his knees
Matt plunged the knife right into Edd
But it hit Edd's lucky can instead
Edd felt like he was in the clear
That the little girl clapped her hands
C'mon knock it off, guys!"
But her powers had no effect on him
So Tom kicked her out the door
And said "Don't come back anymore!
The curse on Edd and Matt was gone
So they both turned and looked at Tom
"Why couldn't she possess your mind?
"You can't possess something twice."
Possessed Edd and Matt strangling each other (the YouTube thumbnail for Trick or Threat).
