Here's an attempt at doing a 'runner'. Not sure if the ending is a bit predictable. Let me know!
Int. Front Room. Christmas Day
A man, woman and a young girl are sat by a Christmas tree. The woman hands the man a present.
Woman: This is from me, darling.
Man: Thanks!
The man has great difficulty unwrapping it. He struggles and strains with it.
Woman: D'you want me to get the scissors?
Man: I'm fine.
The man continues struggling. He turns his back on the family as he grunts and strains with the present.
Girl: Why is Daddy making that noise?
Man: Get to your room!
Woman: Lets leave your father to it, dear.
The woman and girl leave the room. The man continues struggling.
Man: C'mon you bastard! C'mon!
CUT TO: Int. Front Room
The woman and girl are taking down the christmas decorations. The man, now with a short beard, is still struggling with the present.
Woman: You don't want me to-
Man: (MADLY) I'M FINE!
Woman: It's been 6 days.
Man: It's coming! It's coming!
The man rips it open. A plain box is inside. He looks at it and starts struggling to open it.
Man: You will be mine! YOU WILL!
CUT TO: Int. Front Room
The man is still struggling with the box. His clothes are now ragged, he has long grey hair and a long beard.
Man: (WHEEZING) C'mon. C'mon.
The woman, also aged, enters the room.
Woman: Give it up.
The man stops struggling. He looks defeated. He shakes his head.
Man: Never!
The man starts struggling again. He gives one large grunt and rips the lid off the box.
Man: At last!
The man puts his hand in the box and pulls out a pair of hand strengtheners/hand grippers.
Man: Oh Darling!
The man starts to struggle as he tries to exercise with the grippers.
ENDS
Quite funny though.
