The nickname of NZ's boat in the America's Cup yacht race a few years ago was 'Black Magic' (because the boat was black and awesome). The Kiwis defended their title in Auckland and a father bought a merchandising cap for his son with the boat's nickname on it. The next morning the kid was at the breakfast table in tears because during the night the boy had seen the cap moving of its own volition.
"I mean really, brothers and sisters. What did this father expect? The cap had Black Magic written on it!"
