In 2006, I taught an English class of 8-year-old Vietnamese children. The lesson was about how to use "there is" or "there are" to state the existence of something. They had a worksheet that was a picture of a farm with various animal pens. To complete it, they had to draw a number of animals and then write sentences describing their picture with "there is" or "there are".
One little boy wrote "There is one goat" and drew a picture of a goat that has haunted my dreams for 15 years. The scanned image (in a file called "Quang's Demon Goat") has also haunted my hard drives since that fateful day. This one-page MÖRK BORG creature is an attempt to exorcise the demon goat from my mind.
