I keep a set of earplugs in my truck at school. I teach shop so I always have them where I can get to them. When we have pep rallies, I am the only one who has earplugs and everyone else threatens to take them for themselves. I also use cotton for earplugs if I don't have mine with me for some reason. Also for the students to use when planing etc.

I was volunteering for First Aid duty at a Rock concert last summer. When the band started playing, some of the local city cops came over to see if we had any earplugs in our first aid supplies. They were quite grateful when one of our attendants handed them 6 pairs. <img src="images/graemlins/smile.gif" alt="" />

Empty .38 hulls, inserted base first of course. They don't work very well tho...
