SAFETY GUIDELINES FOR LASER USERS

DO NOT USE LASER BEAMS TO PLAY PRANKS ON FRIENDS

Using laser beams to play pranks on friends is a classic move, but it's also extremely hazardous to their health and your relationships. Don't do it.

Do not aim laser beams at people's eyes. It's just not worth it.
Be aware of your surroundings and avoid pointing laser beams at pets or animals. They're more likely to run away and cause a stampede.
Keep a safe distance from laser beams. You don't want to get caught in a beam yourself.
Avoid using laser beams in low-light environments. You're not a ninja.
Never use laser beams to cut through a stack of 50 CDs. It's not worth the risk of damaging your hearing or causing a mess.
