Do you have friends or co-workers who are always making off with your pen? Here’s an inexpensive way to “teach them a lesson”. And if they’re wearing a pacemaker they’re really going to get a big surprise. The pen’s sold as a “practical joke” – but right underneath the instructions “press clicker to shock” is the somewhat disturbing warning “may interfere with electrical devices such as pacemakers”. The manufacturer closes out by stating how you “will have absolute pleasure zapping your colleagues and friends with an electric shock”. Alternate Use: While they’re bringing your pacemaker wearing co-worker to the hospital – help yourself to all the office supplies in their desk.
