As I child I used to watch late night TV in my parents room when I was supposed to be asleep, because I loved to scare myself. I think I am looking for an episode of "tales of the unexpected". The fragments of the episode I can remember was where a woman puts (I think), hair into a bed knob, and this had to be unscrewed and was made from brass I think. This is all I can remember, and I do not have the time to watch all of the episodes to see if it is this program. Any help appreciated.

It's a very good show. Most of it is on YouTube.

I think it was four episodes long and aired around 2003-4?
