My Brain Hurts

A citizen of Oxford, England, moved to London, where he soon found himself a little bit too superior to the rest of the population. So in order to fit in to the environment, he had to do a surgery to remove half of his brain.

Very well, he went to a hospital to get it done. The surgeon, however, made a mistake during the operation, and instead of removing half of the brain, he removed the whole thing.

When the patient woke up, his first word was "G'Day!"
