Regular Show, Season 6

Mordecai:
You're dead, dude.

Benson:
What?!

Rigby:
Yeah, man. Don't you remember?

[In another flashback, Benson hangs Halloween decorations on a ladder at the top of the stairs. Mordecai, holding up the beast mask, and Rigby walk up]

Mordecai:
Benson, look at this mask!

Benson:
Aah!

[Benson falls down the stairs and dies. His ghost leaves his body]

Rigby (voice-over):
You've been haunting the house for months.

[Benson's ghost scares Rigby while he's eating cereal. When Rigby screams, Benson flees as if he's also scared. The same happens with Mordecai while he's carrying a box up the stairs. Cut to Mordecai and Rigby in the hallway, with Rigby trying to open a bottle of soda]

Rigby:
No, dude. It's "lefty locky, righty relaxy".

Mordecai:
That doesn't even rhyme!

[Benson's ghost appears again. It sees Mordecai and Rigby and moans in fright as he leaves. The flashback ends]

Benson:
Then what are you guys doing here? You've ruined my office!

Mordecai:
We're not in your office. This is our office.

Rigby:
We got promoted!

Mordecai:
And this isn't our office. [screen zooms out from Mordecai's face] It's a cemetery. [points down as lightning strikes] And that's your grave!

[Cut to Benson's tombstone, which reads "R.I.P. BENSON. 'YOU'RE FIRED'". Benson falls to his knees next to his tombstone]

Benson:
NOOOOOOOO!!!!
