I'm not sure if I can make this into something more substantial or if I'd be dragging it out - if it's a sketch it needs an ending.
(Three men are visible, seated as part of a wider circle).
DAVE
We've still got to be careful Ian. We can't just go walking through walls.
IAN
Why?
DAVE
Because it's a myth.
IAN
No, it isn't.
DAVE
Fine. Well, smile for our new member.
IAN
No.
DAVE
I'm sorry mate, he's got no teeth you see.
TOM
Rotted away?
DAVE
No. Daft twat walked into a wall. Ghosts anonymous isn't just about turning up and saying that we're ghosts, we know that already, but rather we're here to share our experience.
FRED
Not bloody likely.
(The camera drops to Fred. He's sat upright in a coffin, and facing away from the circle)
IAN
Shut it, Fred.
DAVE
Fred's an example of denial.
FRED
No he isn't.
(Dave gets up and walks into Fred's eyeline. Fred jumps and screams in terror)
DAVE
For God's sake, you're a ghost too Fred.
IAN
He thinks we're haunting him
FRED
Why don't you people just bugger off - I'm waiting for the bingo
