Blackadder

Baldrick:
I couldn't sleep when I was little.

Blackadder:
You still are little, Baldrick.

Baldrick:
Yeah, well, when I was even littler, see, we used to live in this big haunted hovel. Every night, my parents were troubled by a visitation from this disgusting ghoul. It was terrible. First there was this unholy smell, and then this tiny, clammy, hairy creature would materialize in the bed between them. Strangely I could never see it myself.

Blackadder:
[absolutely disgusted] Yyyyyes... Tell me, Baldrick, when you left home, did this repulsive entity mysteriously disappear?

Baldrick:
That very day.

Blackadder:
I think then that the mystery is solved. Now, either you leave me alone to think of a plan, or tomorrow we meet our maker - in my case, God; in your case, God-knows... but I'd be surprised if he won any design awards.
