I think the best types are the two-word ones and just normal short ones.

'This is an example of a short story' (This is an actual story, this is just it in my own words):

I was at my friends house, he was in bed. I was playing a game when I heard tapping on the window. I turned around to see the dead body of my friend, hanging out the window. I looked over to his bed, there was still something inside...

Like... wowzer. That was creepy you gotta admit! 

Also, a two-word story:

There was a face staring at me through the window. I'm on the sixth floor.
