My brother, Symon, and I went shopping yesterday, and my brother picked up this shirt:

What is your interpretation of this shirt? Before you read the following words, make a mental note of what you think.
When we first saw the shirt, our interpretation of the shirt was that the wearer gets to do the free exams on others. My brother wore the shirt to school today, and his friends thought the free exam was on him and grabbed him. :P
So what did you think?
