Back in the day, I remember my shop teacher getting pissed on a regular basis because we got a kick out of shining this giant bulky laser pointer on his head while he talked. It was probably no more powerful than a modern keychain laser pointer, but he was always quick to point out that it could cause severe damage to the eyes. Needless to say, he would have loved this hat. A close-up of the warning label is available after the break.
