TomCampbell's got a sketch on here'Happy Ending', 'tis very good 
got me thinking... so here is my extened version.
Starts off the same (with a wee extra couple of lines in) then runs onto my extended scene.
INT: MASSAGE PARLOUR
FAT MAN is lay on a bed recieving a massage from KOREAN FEMALE. The man groans as he has his back rubbed intensely.
KOREAN FEMALE
This good, Mr. Woberts?
FAT MAN
Mmm...fantastic.
KOREAN FEMALE
You want happy ending, Mr. Woberts
FAT MAN (shocked, then suddenly overjoyed)
Ohhh, yes please!
KOREAN FEMALE
You pay extra for happy ending Mr. Wberts?
FAT MAN
Yes, Yes.
HE HANDS OVER SOME CASH FROM HIS JACKET POCKET WHICH IS DRAPED OVER THE NEAR BY CHAIR.
KOREAN FEMALE
Very well...on your back please, Mr. Woberts.
FAT MAN rolls over smiling to himself. Camera focuses on his face as his smile turns to confusion. Camera changes to his perspective where PRINCE appears decked in a white suit. He dismounts a white horse, holding a silver slipper.
PRINCE
At last, I have found you. You must return to my castle where we will be wed.
FAT MAN stares, confused by the whole situation. KOREAN FEMALE is smiling widely along with PRINCE.
FAT MAN
This isn't what I expected... I... I... wanted...
KOREAN FEMALE
Oh, you want ewotic happy ending, Mr. Woberts, yes?
FAT MAN
Yes, yes, that's more like it... ewotic, I mean erotic.
KOREAN FEMALE
You pay much, much more extra for ewotic happy ending Mr. Woberts?
HE EAGERLY HANDS OVER AN EVEN LARGER SOME OF CASH FROM HIS JACKET POCKET.
KOREAN FEMALE
On your tummy Mr. Woberts.
HE PROMPTLY TURNS OVER WITH A DIRTY GRIN.
AGAIN, CAMERA CHANGES TO HIS PERSPECTIVE. PRINCE HAS APPEARED AGAIN, THIS TIME BRANDISHING A TUBE OF LUBRICATION AND AN EIGHT INCH GLASS DILDO.
FAT MAN LOOKS BEFUDDLED AND GRIMACES.
