I was thinking today. (I do this way too often. I've been given pills, but they don't help much.) What about? Time
Actually, I was thinking about Time and the English Language. Despite all the parsing errors that creep into the language, I think it's pretty usable. But if you think about some of the expressions used in describing time, you get a very odd image.
For example, take a random trio of phrases:
Time is short
The night is young
A hairy moment
What you get, is an image where Time is much like a troll-cub. (Short, hairy, and young). And that is probably one of the more tame examples. (Don't even think about using "half-past" in one of your images. Eww!)
