During our schoolwide health fair, in conjunction with Jump Rope For Heart, the Heart Association was doing a presentation where the students were using stethescopes. They were to use the alcohol preps to clean the earpieces between uses. One student was observed putting the stethescope in his ears without doing this. The presenter looked at the two and the kindergarten student who had used the stethescope and the student said, "It's OK, we have the same wax. He's my brother."
