Goodbye

Ren winced as he washed the cut on his neck.
Just as he dug the knife in, he came to his senses and stopped.
He'd thrown the knife to the floor, and quickly scrambled away from it.
And now, as he covered up his cut and sucked down a can of beer, he was starting to feel better.
Well, not better. Just not sad.
Ever since the murder, angry and insane is as "better" as he could get.
But to him, that didn't matter. Stimpy was finally gone. Life without that idiot was perfect either way.
Again, that's just what he TRIED to believe...
He sucked down the rest of his beer, and as he reached for another, there was a loud knock at the door.
"F.B.I, open up," a man's voice boomed from outside.
Thankfully, the lights were off, and the curtains were shut.
"You have 3 seconds to open the door, or I will have to kick it down."
"Ah, stop your whinin'," Ren said, just loud enough for him to hear. "I'm comin'."
He slowly grabbed the gun he kept hidden, and crept towards the door.
He opened the door fearlessly.
"Marlin Höek, you are under arre-"
He was cut off by a loud gunshot.
The cop dropped to his knees, coughed up some blood, and died.
Ren slowly started to laugh, chuckling and giggling, until he burst into a full-out evil laugh.
"AHHH HAHAHAHAHA!"
He buried the body somewhere far away, and destroyed all evidence.
As he lit a cigarette, he said, "Guess it's time to move again."
