Inspired by a shop sign I saw today.
INT. a small room - day
The room is very small and is just a bed and a chair and Chinese charts and diagrams on the walls. An old man who looks a lot like Mr Miyagi is sat on the chair.
OLD MAN
Please, sit on bed
The young man complies.
MAN
Well, I've been having problems, err, getting it up, and I've heard good things about these Chinese remedy things and I saw your sign out front that said...
The old man moves next to the man, rubs his hands then holds them near the man's crotch. He slowly moves them back towards himself whilst exhaling and as he does so, a bulge begins to appear in the man's crotch area.
MAN
Wow. Thank you so much.
The old man goes into a draw and gets out a tube of something and hands it to the man.
OLD MAN
Use this twice a day. Wax on, wack off.
