The scene opens up on the Freddy's BBQ sign, on it is Karaoke night.  As the camera fades in side there is two girls on stage singing "Hit me Baby one more time" by Britney Spears.  The camera focuses in on Mack standing in line. 
"You know I was heading to South Carolina for the card, until I heard that there was Karaoke going on."
Announcer: "Up next is Mack, singing the Scooby-Doo Theme."
Mack gets on the stage and the music starts.
"Scooby-Dooby-Doo, Where Are You?
I got to kick your butt now.
Scooby-Dooby-Doo, Where Are You?
I need no help for you now.
Come on Scooby-Doo, I see you
pretending you got a chance
But you're no fooling me
'cause I can see, the way you shake in fear.
You know you got to lose
So Scooby-Doo be ready to lay flat
[Back up in song] Uh-uh Uh-uh
Don't be upset!
And Scooby-Doo if you come through you're going to be in AOD!
That's some crap!
Scooby-Dooby-Doo, where are you
You think you're ready and willing
If I count on you
Scooby- Doo, I know I'll get that belt."
The crowd goes wild and Mack walks off stage.  He walks up to the camera.
"Scooby in a day you will met your Fate and fall to my Wrath.  FEAR ME AND FEAR THE WRATH OF THE FATE. "
As the camera fades out the announcer can be heard.
"Up next  Holly singing "At Last" by Etta James.
