I have a long relationship with free ear plugs like these being offered by Hearos. My dad was in a rock band during my childhood so I spent quite a bit of time on the road. I routinely ignored the normal perks, like being backstage and groupies, in exchange for making up games like “how many ear plugs can I stick up my nose?” (six) and “can I eat this jar of Reese's Pieces in under 10 minutes?” (no). I have to say it was a well spent youth.
