Musicians can write songs that can loop, so why can't authors write stories that loop.

The Time Machine:
"Oh my God, it works!"
The machine was humming, it was just about ready. I adjusted a few things, tightened a few screws, made sure everything was fastened in place. There were oiled rags, and rubbish lying everywhere, it was a right mess. So I gathered up all the rubbish and packed it into an old empty cardboard box. I used packing tape to close it up. It was bulging considerably, so I went outside to put the rubbish in the bin.

But then I saw our neighbour's cat, Mr. Tibbles hiding up a tree in my front yard. So I used my superhuman brawndo muscles to shake the tree, and the cat fell down. I took the cat into the basement and placed it in the time machine. I sent it to 2 million years in the future. Yeah, take that, Finklestein! Then, my wife came down into the basement and handed me a letter. It read "Dear wife of God. I am assuming you are the wife of God, because if you are reading this, it means I have invented a working time machine, and sent the letter though time, and therefore I am God."

"Who wrote this?" my wife asked me.
"I don't know" I replied. "Now please leave, I have just killed Mr. Tibbles, and I am thinking about using the time machine on myself".
"Ok" she said, and without further ado, went outside to wave at a passing bus.
I put the letter into the time machine and set it for 1 minute into the past. If it did work, then my wife would recieve the letter, already written, and she would hand it to me to send to the past. How did that letter exist?

I decided not to answer that question as I deemed it rhetorical, so I sneezed three times and did the chicken dance, such was my obsessive compulsive disorder that plays a major part in this story (yes, I broke the fourth wall, get over it. It's not hard. The wall is considerably smaller now that I knocked it down. It's not too hard to get over it. You're welcome.) So I then went into the time machine and set it for five minutes in the past.

Return to the begining of the story and read again.
It LOOPS!
